The Singular Value Expansion for Arbitrary Bounded Linear Operators
Mathematics, 2020 The singular value decomposition (SVD) is a basic tool for analyzing matrices. Regarding a general matrix as defining a linear operator and choosing appropriate orthonormal bases for the domain and co-domain allows the operator to be represented as ...

Viewing *-multiplication operators between Orlicz spaces
Filomat, 2020 In this paper, Lambert multipliers acting between Orlicz spaces are characterized based on some properties of conditional expectation operators. We provide a necessary and sufficient condition for the *-multiplication operators to have closed range.

Properties of multiplication operators on the space of functions of bounded φ-variation
Open Mathematics, 2021 In this paper, the functions u∈BVφ[0,1]u\in B{V}_{\varphi }\left[0,1] which define compact and Fredholm multiplication operators Mu{M}_{u} acting on the space of functions of bounded φ\varphi -variation are studied.

Multiplication Operators on Weighted Banach Spaces of a Tree
, 2015 We study multiplication operators on the weighted Banach spaces of an infinite tree. We characterize the bounded and the compact operators, as well as determine the operator norm.

, 2011 In this paper, we combine methods of complex analysis, operator theory and conformal geometry to construct a class of Type II factors in the theory of von Neumann algebras, which arise essentially from holomorphic coverings of bounded planar domains. One

Asymmetric truncated Toeplitz operators equal to the zero operator [PDF]
, 2016 Asymmetric truncated Toeplitz operators are compressions of multiplication operators acting between two model spaces. These operators are natural generalizations of truncated Toeplitz operators.

OPERATOR-VALUED MULTIPLICATION OPERATORS ON WEIGHTED FUNCTION SPACES
Demonstratio Mathematica, 2002 Let \(X\) be a completely regular Hausdorff space, \(E\) a Hausdorff topological vector space, \(V\) a Nachbin family of weights on \(X\), and \(CV_b(X,E)\) the weighted space of continuous \(E\)-valued functions on \(X\). Let \(B(E)\) be the vector space of all continuous linear mappings from \(E\) into itself, endowed with the topology of uniform ...

Multiplication operators in Köthe–Bochner spaces
Journal of Mathematical Analysis and Applications, 2011 Let X be a Banach space and E an order continuous Banach function space over a finite measure mu. We prove that an operator T in the Kothe-Bochner space E(X) is a multiplication operator (by a function in L(infinity)(mu)) if and only if the equality T(g < f, x*> x) = g < T(f), x*> x holds for every g is an element of L(infinity)(mu), f is an element of

The essential norm of multiplication operators acting on Orlicz sequence spaces
, 2020 We calculate the measure of non-compactness or the essential norm of the multiplication operator Mu acting on Orlicz sequence spaces lφ. As a consequence of our result, we obtain a known criteria for the compactness of multiplication operator acting on ...
