Weighted almost convergence and related infinite matrices
Journal of Inequalities and Applications, 2018 The purpose of this paper is to introduce the notion of weighted almost convergence of a sequence and prove that this sequence endowed with the sup-norm ∥ ⋅ ∥ ∞ ${\Vert \cdot \Vert } _{\infty}$ is a BK-space. We also define the notions of weighted almost

Genuine modified Bernstein–Durrmeyer operators
Journal of Inequalities and Applications, 2018 The present paper deals with genuine Bernstein–Durrmeyer operators which preserve some certain functions. The rate of convergence of new operators via a Peetre K $\mathcal{K}$-functional and corresponding modulus of smoothness, quantitative Voronovskaya ...

Virasoro vertex operator algebras, the (nonmeromorphic) operator product expansion and the tensor product theory [PDF]
, 1995 In the references [HL1]--[HL5] and [H1], a theory of tensor products of modules for a vertex operator algebra is being developed. To use this theory, one first has to verify that the vertex operator algebra satisfies certain conditions.

A Dunkl type generalization of Szász operators via post-quantum calculus
Journal of Inequalities and Applications, 2018 The object of this paper to construct Dunkl type Szász operators via post-quantum calculus. We obtain some approximation results for these new operators and compute convergence of the operators by using the modulus of continuity.

From Operator Algebras to Superconformal Field Theory [PDF]
, 2010 We make a review on the recent progress in the operator algebraic approach to (super)conformal field theory. We discuss representation theory, classification results, full and boundary conformal field theories, relations to supervertex operator algebras ...

Extended Weyl-Type Theorems for Direct Sums
Demonstratio Mathematica, 2014 In this paper, we study the stability of extended Weyl and Browdertype theorems for orthogonal direct sum S⊕T, where S and T are bounded linear operators acting on Banach space.

Minimal and Maximal Operator Spaces and Operator Systems in Entanglement Theory [PDF]
, 2010 We examine k-minimal and k-maximal operator spaces and operator systems, and investigate their relationships with the separability problem in quantum information theory. We show that the matrix norms that define the k-minimal operator spaces are equal to

Sequence spaces M ( ϕ ) $M(\phi)$ and N ( ϕ ) $N(\phi)$ with application in clustering
Journal of Inequalities and Applications, 2017 Distance measures play a central role in evolving the clustering technique. Due to the rich mathematical background and natural implementation of l p $l_{p}$ distance measures, researchers were motivated to use them in almost every clustering process ...

Ergodic Theory, Dynamic Mode Decomposition, and Computation of Spectral Properties of the Koopman Operator [PDF]
SIAM Journal on Applied Dynamical Systems, 2016 We establish the convergence of a class of numerical algorithms, known as dynamic mode decomposition (DMD), for computation of the eigenvalues and eigenfunctions of the infinite-dimensional Koopman operator.
