Hausdorff operators on homogeneous spaces of locally compact groups

Журнал Белорусского государственного университета: Математика, информатика, 2020
Hausdorff operators on the real line and multidimensional Euclidean spaces originated from some classical summation methods. Now it is an active research area. Hausdorff operators on general groups were defined and studied by the author since 2019.

Bounds of a Unified Integral Operator via Exponentially s,m-Convexity and Their Consequences

Journal of Function Spaces, 2020
Various known fractional and conformable integral operators can be obtained from a unified integral operator. The aim of this paper is to find bounds of this unified integral operator via exponentially s,m-convex functions.

Applications for Unbounded Convergences in Banach Lattices

Fractal and Fractional, 2022
Several recent papers investigated unbounded convergences in Banach lattices. The focus of this paper is to apply the results of unbounded convergence to the classical Banach lattice theory from a new perspective.

Dynamics of a Compact Operator [PDF]

ISRN Mathematical Analysis, 2011
Let be a compact linear (or more generally affine) operator from a Banach space into itself. For each , the sequence of iterates , , 1, and its averages , 1, are either bounded or approach infinity.

Fixed Points of Closed and Compact Composite Sequences of Operators and Projectors in a Class of Banach Spaces

Journal of Applied Mathematics, 2013
Some results on fixed points related to the contractive compositions of bounded operators in a class of complete metric spaces which can be also considered as Banach’s spaces are discussed through the paper.

Fuzzy Convergence Sequence and Fuzzy Compact Operators on Standard Fuzzy Normed Spaces

مجلة بغداد للعلوم, 2021
The main purpose of this work is to introduce some types of fuzzy convergence sequences of operators defined on a standard fuzzy normed space (SFN-spaces) and investigate some properties and relationships between these concepts.

Compact $AC(\sigma)$ operators

, 2008
All compact $AC(\sigma)$ operators have a representation analogous to that for compact normal operators. As a partial converse we obtain conditions which allow one to construct a large number of such operators. Using the results in the paper, we answer a

The ideal of Lipschitz classical p-compact operators and its injective hull

Moroccan Journal of Pure and Applied Analysis, 2022
We introduce and investigate the injective hull of the strongly Lipschitz classical p-compact operator ideal defined between a pointed metric space and a Banach space.

Geometric spectral theory for compact operators [PDF]

, 2013
For an n-tuple A = (A1,··· ,An) of compact operators we define the joint point spectrum of A to be the set p(A) = {(z1,··· ,zn) ∈ C n : ker(I + z1A1 + ··· + znAn) 6 (0)}.

Equivalence after extension for compact operators on Banach spaces

, 2015
In recent years the coincidence of the operator relations equivalence after extension and Schur coupling was settled for the Hilbert space case, by showing that equivalence after extension implies equivalence after one-sided extension.
