Abstract:

Abstract We compute the modular transformation formula of the characters for a certain family of (finitely or uncountably many) simple modules over the simple $\mathcal{N}=2$ vertex operator superalgebra of central charge $c_{p,p^{\prime }}=3\left (1-\frac{2p^{\prime }}{p}\right ),$ where (p, p′) is a pair of coprime positive integers such that p ≥ 2. When p′ = 1, the formula coincides with that of the $\mathcal{N}=2$ unitary minimal series found by F. Ravanini and S.-K. Yang. In addition, we study the properties of the corresponding “modular S-matrix”, which is no longer a matrix if p′≥ 2.

Abstract:

This paper proposes a power qulity disturbances classification method based on generalized S-Transform(GST) and maximum similarity principle. The GST gauss window changes self-adaptively with the main frequency of the power quality disturbances. The standard modular time-frequency matrixes are constructed by selecting special segment of GST modular matrixes of every category disturbance and scale-transforming based on bilinear interpolation. The test disturbances are dealed with same as the means of standard modular construction. Especially, for representing the difference of sags and swells,

Abstract:

This work’s novelty lies in using the simplest group i.e. Γ(2) ≃ S 3 modular symmetry implemented on the canonical seesaw to explain neutrino phenomenology. Here, we construct and classify models based on the doublet and singlet representations of supermultiplets under S 3 discrete symmetry along with their respective modular weights, allowing a mass matrix for the neutrino sector with minimal use of free parameters, namely models A, B, C, D. These modular symmetries become advantageous in avoiding the requirements of multiple flavon fields and the intricacies of vacuum alignments. In this way

Abstract:

In our work, we constructed an inverse seesaw(2,3) model using the modular invariance approach. The predictability of the model is enhanced and the number of flavon fields reduced by using this modular invariance approach. Here, we have used the S 4 modular group to assist us design the model. Within the present framework, the neutrino phenomenology can be studied with the help of the non-trivial transformation of Yukawa couplings. The right-handed neutrino mass can be experimentally verified by reducing it to the TeV range via the application of the inverse seesaw mechanism. In this work, we

We discuss the general ideology of the computation of string loop corrections to the effective action for the massless modes of the string. Both the S-matrix and the sigma-model approaches are presented. It is emphasized that the effective action is a more general and better defined object than the S-matrix. In particular, it is finite in spite of modular infinities that may be present in loop amplitudes computed near a “wrong” vacuum. The case of the disc topology in the open-closed string theory is treated in some detail. Some issues concerning the soft dilaton vertex operators related to th

Using the decomposition of rational conformal filed theory characters for the $\Z_k$ parafermion quantum Hall droplets for general $k=2,3,\dots$, we derive analytically the full modular $S$ matrix for these states, including the $\uu$ parts corresponding to the charged sector of the full conformal field theory and the neutral parafermion contributions corresponding to the diagonal affine coset models. This precise neutral-part parafermion $S$ matrix is derived from the explicit relations between the coset matrix and those for the numerator and denominator of the coset and the latter is express

Abstract We make an investigation of modular Γ 5 ′ ≃ A 5 ′ group in inverse seesaw framework. Modular symmetry is advantageous because it reduces the usage of extra scalar fields significantly. Moreover, the Yukawa couplings are expressed in terms of Dedekind eta functions, which also have a q expansion form, generally utilized to achieve numerical simplicity. Our proposed model includes six heavy fermion superfields i.e., N R i , S L i and a weighton. The study of neutrino phenomenology becomes simplified and effective by the usage of A 5 ′ modular symmetry, which provides us a well defined m

Abstract:

Cryptography is commonly used to secure communication and data transmission over insecure networks through the use of cryptosystems. A cryptosystem is a set of cryptographic algorithms offering security facilities for maintaining more cover-ups. A substitution-box (S-box) is the lone component in a cryptosystem that gives rise to a nonlinear mapping between inputs and outputs, thus providing confusion in data. An S-box that possesses high nonlinearity and low linear and differential probability is considered cryptographically secure. In this study, a new technique is presented to construct cry

Abstract TQFTs, or anyon theories, have a large amount of addition mathematical structure which we explore in this chapter.

We define the S-matrix in terms of diagrams, and the T-matrix in terms of twists. We show how the S- and T-matrices are related to the modular group of diffeomorphisms of the torus, and related further to the notion of central charge. We discuss how the many constraints on TQFTs enables o

Abstract Atiyah systematized the general principles of topological quantum field theories in terms of the mathematics of gluing together manifolds and combining vector spaces. A TQFT roughly is a partition function Z(M) with M a manifold, that returns a number of M has no boundary and a wavefunction on the boundary if M has a boundary. Manifolds can be glued together on their boundaries by taking inner products of wavefunctions. We roughly describe this approach and describe how it relates to the physics of anyons as we have discussed in prior chapters. We also introduce the important notion o
