Abstract:

A general way to construct chain models with certain Lie algebraic or quantum Lie algebraic symmetries is presented. These symmetric models give rise to series of integrable systems. As an example the chain models with An symmetry and the related Temperley–Lieb algebraic structures and representations are discussed. It is shown that corresponding to these An symmetric integrable chain models there are exactly solvable stationary discrete-time (resp. continuous-time) Markov chains with transition matrices (resp. intensity matrices) having spectra which coincide with the ones of the corresponding integrable models.

Abstract:

The contour argument was introduced by Peierls for two dimensional Ising model. Peierls benefited from the particular symmetries of the Ising model. For non-symmetric models the argument was developed by Pirogov and Sinai. It is very general and rather difficult. Intuitively clear that the Peierls argument does work for any symmetric model. But contours defined in Pirogov–Sinai theory do not work if one wants to use Peierls argument for more general symmetric models. We give a new definition of contour which allows relatively easier proof to the main result of the Pirogov–Sinai theory for symmetric models. Namely, our contours allow us to apply the classical Peierls argument (with contour removal operation).

Abstract:

This Special Issue covers symmetric and asymmetric data that occur in real-life problems. We invited authors to submit their theoretical or experimental research to present engineering and economic problem solution models that deal with symmetry or asymmetry of different data types. The Special Issue gained interest in the research community and received many submissions. After rigorous scientific evaluation by editors and reviewers, seventeen papers were accepted and published. The authors proposed different solution models, mainly covering uncertain data in multi-criteria decision-making problems as complex tools to balance the symmetry between goals, risks, and constraints to cope with the complicated problems in engineering or management. Therefore, we invite researchers interested in the topics to read the papers provided in the Special Issue.

Abstract:

This paper investigates cylindrically symmetric distribution of an anisotropic fluid under the expansion-free condition, which requires the existence of a vacuum cavity within the fluid distribution. We have discussed two families of solutions that further provide two exact models in each family. Some of these solutions satisfy the Darmois junction condition while some show the presence of a thin shell on both boundary surfaces. We also formulate a relation between the Weyl tensor and energy density.

Abstract:

Model Checking is a powerful method for the formal verification of concurrent systems. It explores automatically the state-space of a model that represents the system to prove its correctness in relation to formal specifications, which are described using some temporal logic. Despite its importance and wide application, Model Checking suffers with the state-space explosion: the number of states of a model is exponential to its size; thus it limits the size of the models that may be verified. Many techniques were proposed to overcome this problem. Among them, the use of abstractions is considered one of the most general and efficient. The adoption of abstractions consists of generating a reduced model from the original model by merging or removing states that are irrelevant to the specification being verified. Another technique is the symmetry reduction. It is based on the observation that several models present some level of symmetry, and states considered equivalent can be grouped. Thus, the state-space to be considered is significantly smaller and the exploration of only one of the states of the same group is sufficient to prove the correctness of some propriety. This work combines both techniques to produce reduced models that can be verified at feasible time. It presents a methodology to generate semiautomatic abstractions, based on the model symmetry. The key idea is that, for the verification of certain proprieties, the removal of symmetric components of a model has a small impact on information loss caused by the abstractions since its symmetric counterpart is still represented. The methodology defines modeling premises to make the abstraction adoption semiautomatic, i.e., without the need to alter the model description. Moreover, it presents abstraction patterns based on the system symmetry and shows which specifications are consistent with each pattern. The techniques presented in this work are specially useful on the verification of computation systems that present considerable replication of structures. This characteristic can be observed in memories, caches, bus protocols, multi-processes applications and network protocols. In this work the model of a P2P Live Streaming application was implemented to validate the methodology. At this model each participant receives and forwards data to its partners to reconstruct the original live stream. The fact that all peers are distinct processes that share the same code makes this model highly symmetric and thus a valid example. The reductions obtained by the methodology proved to be very significant. I.e, the calculation of the number of reachable states of the original model, from a total of approximately 273 possible states, has not finished after more than two weeks of intensive computation. In contrast, the same computation for the reduced models finished in less than two minutes in all cases and the maximum number of reachable states found was approximately 219.
A Verificação de Modelos é uma técnica poderosa de verificação automática de sistemas concorrentes. Ela explora automaticamente os estados de um modelo que representa o sistema para provar sua correção com relação a especificações formais, descritas usando alguma lógica temporal. Apesar de sua importância e ampla aplicação, a Verificação de Modelos sofre com o problema da explosão de estados: o número de estados do modelo é exponencial ao seu tamanho; isto limita o tamanho dos modelos possíveis de serem verificados. Diversas técnicas foram propostas para contornar o problema. Dentre elas, o uso de abstrações é considerada uma das mais genéricas e eficientes. A adoção de abstrações consiste em gerar um modelo reduzido a partir do modelo original através da fusão ou remoção de estados que supõe-se irrelevantes com relação à propriedade sendo verificada. Outra técnica é a redução por simetria. Ela baseia-se na observação que diversos sistemas apresentam considerável grau de simetria, e estados considerados equivalentes podem ser agrupados. Assim o espaço dos estados a ser considerado é significantemente menor e a exploração de apenas um dos estados do mesmo grupo é suficiente para provar a correção de alguma propriedade. Este trabalho combina ambas as técnicas para produzir modelos reduzidos, que podem ser verificados em tempo factível. É apresentada uma metodologia para gerar abstrações semiautomáticas, baseada na simetria do modelo. A ideia chave é que, na verificação de certas propriedades, a remoção de componentes simétricos de um modelo tem um impacto pequeno na perda de informação causada pelas abstrações já que a contra-parte simétrica ainda está presente. A metodologia define premissas de modelagem para tornar a adoção das abstrações semiautomática, ou seja, sem a necessidade de alterar a descrição do modelo. Além disso, são apresentados padrões de abstrações baseados na simetria do sistema e mostra-se quais especificações são consistentes com cada padrão. As técnicas apresentadas neste trabalho são especialmente úteis na verificação de sistemas de computação que apresentam uma considerável replicação de estrutura. Tal característica pode ser observada em memórias, caches, protocolos de barramento, programas com vários processos e protocolos de rede. Foi implementado no trabalho o modelo de uma rede P2P Live Streaming para validar a metodologia. Neste modelo cada participante recebe e encaminha dados para seus parceiros para reconstruir o conteúdo ao vivo original. O fato de todos os participantes serem processos distintos que compartilham o mesmo código torna este modelo altamente simétrico e assim um exemplo válido. A redução obtida com a metodologia provou ser bastante significativa. Por exemplo, o cálculo do número de estados alcançáveis do modelo original, de um total de aproximadamente 273 estados possíveis, não terminou após mais de duas semanas de computação intensa. Em contrapartida, a mesma computação para os modelos reduzidos terminou em menos de três minutos em todos os casos e o número máximo encontrado de estados alcançáveis foi de aproximadamente 219.

Abstract:

Condensation is an emergent phenomenon in complex systems that is observed in both physical and social sciences, from granular polydisperse spheres to macroeconomic studies. The critical behaviour of condensation in such systems is of continual interest in research. In this thesis we study this in the context of interacting particle systems, in particular the recently introduced explosive condensation process. We firstly provide a review of the mathematical foundations of interacting particle systems from the aspects of Markov processes. This includes the formulation of factorised hop rates, stationary product measures, the equivalence of ensembles and how these properties are related to condensation. Subsequently, we give a review of key interacting particle systems of interest, namely the zero-range process, inclusion process and the explosive condensation process. We then introduce two models that have similar stationary weights scaling as the explosive condensation process and include them in our study in the thermodynamic limit. The density and the maximum site occupation are derived under the stationary distribution, and from this we are able to identify the choice of parameters that could lead to a phase transition. Exact results for these models using the generator are di�cult to obtain. For the main results of this study, we therefore analyse the formation of condensate using a heuristic approach. The microscopic interactions leading to the formation of an explosive condensate are structurally studied, and this leads to a comprehensive model with a timescale analysis. The time to condensation is shown to vanish as the thermodynamic limit is reached, depending on the choice of parameter values. Throughout the thesis, theoretical results are supported by Monte Carlo simulation and numerical calculations where appropriate. A modification of the conventional Gillespie algorithm is proposed. The new algorithm improves e�ciencies but is also able to preserve key stochastic properties, and is used throughout the simulation of the main findings.

Abstract:

Scopo della modellizzazione delle stringhe di DNA è la formulazione di modelli matematici che generano sequenze di basi azotate compatibili con il genoma esistente. In questa tesi si prendono in esame quei modelli matematici che conservano un'importante proprietà, scoperta nel 1952 dal biochimico Erwin Chargaff, chiamata oggi "seconda regola di Chargaff". I modelli matematici che tengono conto delle simmetrie di Chargaff si dividono principalmente in due filoni: uno la ritiene un risultato dell'evoluzione sul genoma, mentre l'altro la ipotizza peculiare di un genoma primitivo e non intaccata dalle modifiche apportate dall'evoluzione. Questa tesi si propone di analizzare un modello del secondo tipo. In particolare ci siamo ispirati al modello definito da da Sobottka e Hart. Dopo un'analisi critica e lo studio del lavoro degli autori, abbiamo esteso il modello ad un più ampio insieme di casi. Abbiamo utilizzato processi stocastici come Bernoulli-scheme e catene di Markov per costruire una possibile generalizzazione della struttura proposta nell'articolo, analizzando le condizioni che implicano la validità della regola di Chargaff. I modelli esaminati sono costituiti da semplici processi stazionari o concatenazioni di processi stazionari. Nel primo capitolo vengono introdotte alcune nozioni di biologia. Nel secondo si fa una descrizione critica e prospettica del modello proposto da Sobottka e Hart, introducendo le definizioni formali per il caso generale presentato nel terzo capitolo, dove si sviluppa l'apparato teorico del modello generale.

Abstract:

This paper attempts to study GARCH-type models, with emphasis on fitting GARCH models to exchange rate return series. The symmetric GARCH(1,1) model is compared with the asymmetric EGARCH(1,1) model. Both models are analysed with different conditional distributions, namely Normal, Student's t and skew Student's t for the return innovation. Parameter estimation is performed using a maximum-likelihood approximation. The model performance is assessed by looking at the lowest AIC and BIC. Four exchange rate returns are studied using daily data over the period from 2002 to 2015. Moreover, essential ideas of return time series and stylised facts will be analysed. Our results indicate that the asymmetric GARCH model improves generally estimation with fat-tailed densities in the conditional variance. Furthermore, persistence has found to be reduced with the use of heavy-tailed distributions. Asymmetry presence has been detected in the EGARCH model. Besides, we found that "good news" tend to increase volatility in comparison with "bad news".
Syftet med uppsatsen är att studera modeller av GARCH-typ, och fokus ligger på att anpassa GARCH-modeller efter växelkurstidsserier. Den symmetriska GARCH(1,1)-modellen jämförs med den asymmetriska EGARCH(1,1)-modellen. Modellerna analyseras för olika fördelningar, såsom normal- och t-fördelning, på avkastningarnas brustermer. För att estimera parametrarna används maximum likelihood-metoden. Modellens prestanda bedöms sedan utifrån AIC- och BIC-kriterierna. Studien är baserad på daglig data från fyra valutapar under perioden 2002 till 2015. Resultaten indikerar att den asymmetriska GARCH-modellen förbättrar estimeringen generellt sett. Genom att använda tjocksvansade fördelningar finner man att persistensen minskar. EGARCH-modellen fångar dessutom upp asymmetrier i avkastningarna, på så sätt att volatiliteten ökar mer vid "goda nyheter" än vid "dåliga nyheter".

Abstract:

In this thesis we review some aspects of Yang-Baxter deformations of semi-symmetric space sigma models. We start by giving a short review of the sigma model description of superstrings and then we offer a self contained introduction to the Yang-Baxter deformation technique. We then show how to obtain an integrable deformation of the hybrid sigma model. Also, we show that the gravity dual of beta-deformed ABJM theory can be obtained as a Yang-Baxter deformation. This is done by selecting a convenient combination of Cartan generators in order to construct an Abelian r-matrix satisfying the classical Yang-Baxter equation.
Nesta tese revisamos alguns aspectos das deformações de Yang-Baxter de modelos sigma em espaços semi-simétricos. Damos uma breve revisão do modelo sigma de supercordas e, em seguida, oferecemos uma introdução ao método de deformação de Yang-Baxter. Em seguida, mostramos como obter uma deformação integrável do modelo sigma híbrido. Além disso, mostramos que o dual gravitacional da teoria ABJM beta-deformada pode ser obtida como uma deformação de Yang-Baxter. Isso é feito selecionando-se uma combinação conveniente de geradores de Cartan para construir uma matriz r Abeliana satisfazendo a equação clássica de Yang-Baxter.

Neste trabalho foi proposto o modelo linear parcial generalizado simétrico, com base nos modelos lineares parciais generalizados e nos modelos lineares simétricos, em que a variável resposta segue uma distribuição que pertence à família de distribuições simétricas, considerando um preditor linear que possui uma parte paramétrica e uma não paramétrica. Algumas distribuições que pertencem a essa classe são as distribuições: Normal, t-Student, Exponencial potência, Slash e Hiperbólica, dentre outras. Uma breve revisão dos conceitos utilizados ao longo do trabalho foram apresentados, a saber: análise residual, influência local, parâmetro de suavização, spline, spline cúbico, spline cúbico natural e algoritmo backfitting, dentre outros. Além disso, é apresentada uma breve teoria dos modelos GAMLSS (modelos aditivos generalizados para posição, escala e forma). Os modelos foram ajustados utilizando o pacote gamlss disponível no software livre R. A seleção de modelos foi baseada no critério de Akaike (AIC). Finalmente, uma aplicação é apresentada com base em um conjunto de dados reais da área financeira do Chile.
In this work we propose the symmetric generalized partial linear model, based on the generalized partial linear models and symmetric linear models, that is, the response variable follows a distribution that belongs to the symmetric distribution family, considering a linear predictor that has a parametric and a non-parametric component. Some distributions that belong to this class are distributions: Normal, t-Student, Power Exponential, Slash and Hyperbolic among others. A brief review of the concepts used throughout the work was presented, namely: residual analysis, local influence, smoothing parameter, spline, cubic spline, natural cubic spline and backfitting algorithm, among others. In addition, a brief theory of GAMLSS models is presented (generalized additive models for position, scale and shape). The models were adjusted using the package gamlss available in the free R software. The model selection was based on the Akaike criterion (AIC). Finally, an application is presented based on a set of real data from Chile\'s financial area.

Abstract:

We discuss the target space pseudoduality in supersymmetric sigma models on symmetric spaces. We first consider the case where sigma models based on real compact connected Lie groups of the same dimensionality and give examples using three dimensional models on target spaces. We show explicit construction of nonlocal conserved currents on the pseudodual manifold. We then switch the Lie group valued pseudoduality equations to Lie algebra valued ones, which leads to an infinite number of pseudoduality equations. We obtain an infinite number of conserved currents on the tangent bundle of the pseudodual manifold. Since pseudoduality imposes the condition that sigma models pseudodual to each other are based on symmetric spaces with opposite curvatures (i.e. dual symmetric spaces), we investigate pseudoduality transformation on the symmetric space sigma models in the third chapter. We see that there can be mixing of decomposed spaces with each other, which leads to mixings of the following expressions. We obtain the pseudodual conserved currents which are viewed as the orthonormal frame on the pullback bundle of the tangent space of G tilde which is the Lie group on which the pseudodual model based. Hence we obtain the mixing forms of curvature relations and one loop renormalization group beta function by means of these currents. In chapter four, we generalize the classical construction of pseudoduality transformation to supersymmetric case. We perform this both by component expansion method on manifold M and by orthonormal coframe method on manifold SO(M). The component method produces the result that pseudoduality tranformation is not invertible at all points and occurs from all points on one manifold to only one point where riemann normal coordinates valid on the second manifold. Torsion of the sigma model on M must vanish while it is nonvanishing on M tilde, and curvatures of the manifolds must be constant and the same because of anticommuting grassmann numbers. We obtain the similar results with the classical case in orthonormal coframe method. In case of super WZW sigma models pseudoduality equations result in three different pseudoduality conditions; flat space, chiral and antichiral pseudoduality. Finally we study the pseudoduality tansformations on symmetric spaces using two different methods again. These two methods yield similar results to the classical cases with the exception that commuting bracket relations in classical case turns out to be anticommuting ones because of the appearance of grassmann numbers. It is understood that constraint relations in case of non-mixing pseudoduality are the remnants of mixing pseudoduality. Once mixing terms are included in the pseudoduality the constraint relations disappear.

Abstract:

Undirected, high dimensional and sparse networks are frequently encountered in industrial applications. They contain rich knowledge regarding various useful patterns. Non-negative latent factor (NLF) models have proven to be effective and efficient in acquiring useful knowledge from asymmetric networks. However, they cannot correctly describe the symmetry of an undirected network. For addressing this issue, this work analyzes the NLF extraction processes on asymmetric and symmetric matrices respectively, thereby innovatively achieving the symmetric and non-negative latent factor (SNLF) models for undirected, high dimensional and sparse networks. The proposed SNLF models are equipped with a) high efficiency, b) non-negativity, and c) symmetry. Experimental results on real networks show that they are able to a) represent the symmetry of the target network rigorously; b) maintain the non-negativity of resulting latent factors; and c) achieve high computational efficiency when performing data analysis tasks as missing data estimation.
