Abstract:
Kolmogorov complexity is a theory based on the premise that the complexity of a binary string can be measured by its compressibility; that is, a string’s complexity is the length of the shortest program that produces that string. We explore applications of this measure to graph theory.

Abstract:
After briefly discuss the natural homogeneous Lie group structure induced by Kolmogorov equations in chapter one, we define an intrinsic version of Taylor polynomials and Holder spaces in chapter two. We also compare our definition with others yet known in literature. In chapter three we prove an analogue of Taylor formula, that is an estimate of the remainder in terms of the homogeneous metric.

Abstract:
Hilbert's 13th problem asked whether every continuous multivariate function can be written as superposition of continuous functions of 2 variables. Kolmogorov and Arnold show that every continuous multivariate function can be represented as superposition of continuous univariate functions and addition in a universal form and thus solved the problem positively. In Kolmogorov's representation, only one univariate function (the outer function) depends on and all the other univariate functions (inner functions) are independent of the multivariate function to be represented.

Abstract:
In this thesis we study a class of multidimensional stochastic processes in which a component is the time integral of another. Our interest stems both from the great variety of applications and the challenging structure of the related Kolmogorov backward operators. In fact, while such processes are widely used in physics and finance, the natural geometric framework to study them is considerably far from the standard Euclidean one and still vague. We wish to clarify it developing a new notion of Hölder spaces of any order and proving a Taylor type formula for functions on them. As applic

Abstract:
We consider the problem of testing whether r (>=2) samples are drawn from the same continuous distribution F(x). The test statistic we will study in some detail is defined as the maximum of the circular differences of the empirical distribution functions, a generalization of the classical 2-sample Kolmogorov-Smirnov test to r (>=2) independent samples. For the case of equal sample sizes we derive the exact null distribution by counting lattice paths confined to stay in the scaled alcove $\mathcal{A}_r$ of the affine Weyl group $A_{r-1}$.

This thesis presents a study of hedging errors caused by model mis-specification, making use of a Kolmogorov forward equation with d-function initial conditions. The method is used to calculate the probability distribution of hedging errors at maturity for a number of realistic examples. An analysis of numerical schemes used to solve the Kolmogorov forward equation is presented, making particular use of Fourier transform techniques. Much of the analysis applies to a 'toy' model which captures the main features of the hedging problem. Detailed analysis of a semi-discrete Fourier numerical metho

Abstract:
One of the most useful and best known goodness of fit test is the Kolmogorov one-sample test. The assumptions for the Kolmogorov (one-sample test) test are: 1. A random sample; 2. A continuous random variable; 3. F(x) is a completely specified hypothesized cumulative distribution function. The Kolmogorov one-sample test has a wide range of applications. Knowing the effect fromusing the test when an assumption is not met is of practical importance. The purpose of this research is to analyze the robustness of the Kolmogorov one-sample test to sampling from a finite discrete distribution. The sta

Les méthodes classiques d'apprentissage automatique reposent souvent sur une hypothèse simple mais restrictive: les données du passé et du présent sont générées selon une même distribution. Cette hypothèse permet de développer directement des garanties théoriques sur la précision de l'apprentissage. Cependant, elle n'est pas réaliste dans un grand nombre de domaines applicatifs qui ont émergé au cours des dernières années.Dans cette thèse, nous nous intéressons à quatre problèmes différents en intelligence artificielle, unis par un point commun: tous impliquent un transfer de connaissance d'un

Abstract:
The research in this thesis was motivated by a desire to understand the mixing properties of quasi-two-dimensional flows whose time-dependence arises naturally as a result of fluid-dynamic instabilities. Additionally, we wished to study how flows such as these transition from the laminar into the turbulent regime. This thesis presents a numerical and theoretical investigation of a particular fluid dynamical system introduced by Kolmogorov. It consists of a thin layer of electrolytic fluid that is driven by the interaction of a steady current with a magnetic field produced by an array of bar ma

Nous adaptons le critère de découpage binaire de Kolmogorov-Smirnov aux données de type intervalle, diagramme et taxonomique. Ce critère nécessite un ordre des descriptions des objets. Il est basé sur la fonction de répartition. Nous ordonnons ces données de différentes façons. L'estimation de la fonction de répartition théorique par la fonction de répartition empirique permet l'adaptation de ce critère à ces données. En segmentation, la variable à expliquer est souvent qualitative au départ. Dans notre cas, elle peut être de type intervalle, diagramme ou taxonomique. Différents critères de co

Abstract:
Dans cette thèse, nous analysons le processus d'agrégation et de fragmentation d'agrégats de particules par turbulence, en particulier d'agrégats de fibres. L’originalité de notre étude réside dans le fait que la taille des agrégats et de leurs particules constitutives se situe dans la plage de turbulence inertielle. Les premières expériences sont consacrées à la caractérisation de la force de frottement entre les fibres. Nous avons utilisé un modèle simplifié pour mesurer la force nécessaire pour extraire une fibre d’un réseau. Dans la deuxième expérience, nous avons caractérisé les effets de

Abstract:
The problem of establishing the correct approach to complexity is a very hot and crucial issue to which this dissertation gives some contributions. This dissertation considers two main possibilities, one, advocated by Tsallis and co-workers, setting the foundation of complexity on a generalized, non-extensive , form of thermodynamics, and another, proposed by the UNT Center for Nonlinear Science, on complexity as a new condition that, for physical systems, would be equivalent to a state of matter intermediate between dynamics and thermodynamics.

Abstract:
The aim of the current work is to investigate a series of new subgrid models by employing the Kolmogorov equation of ltered quantities (KEF), which is an exact relation of turbulence in physical space. Different formulations of KEF are derived, including the forms in velocity eld (homogeneous isotropic turbulence, inhomogeneous anisotropic turbulence, homogeneous shear turbulence, homogeneous rotating turbulence), in scalar turbulence and in magnetohydrodynamic turbulence. The corresponding subgrid models are then formulated, for example: - The multi-scale improvement of CZZS model. - A new an

Abstract:
Le traitement de signaux multidimensionnels reste un problème délicat lorsqu'il s'agit d'utiliser des méthodes conçues pour traiter des signaux monodimensionnels. Il faut alors étendre les méthodes monodimensionnelles à plusieurs dimensions, ce qui n'est pas toujours possible, ou bien convertir les signaux multidimensionnels en signaux 1D. Dans ce cas, l'objectif est de conserver le maximum des propriétés du signal original. Dans ce contexte, le théorème de superposition de Kolmogorov fournit un cadre théorique prometteur pour la conversion de signaux multidimensionnels. En effet, en 1957, Kol
