Integro-differential equations with bounded operators in Banach spaces [PDF]

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2022
The paper investigates integro-differential equations in Banach spaces with operators, which are a composition of convolution and differentiation operators.

Spectral resolutions for non-self-adjoint block convolution operators [PDF]

open access: yesOpuscula Mathematica, 2022
The paper concerns the spectral theory for a class of non-self-adjoint block convolution operators. We mainly discuss the spectral representations of such operators. It is considered the general case of operators defined on Banach spaces.

Scale-Invariant General Fractional Calculus: Mellin Convolution Operators

open access: yesFractal and Fractional, 2023
General fractional calculus (GFC) of operators that is defined through the Mellin convolution instead of Laplace convolution is proposed. This calculus of Mellin convolution operators can be considered as an analogue of the Luchko GFC for the Laplace ...

General Fractional Calculus in Multi-Dimensional Space: Riesz Form

open access: yesMathematics, 2023
An extension of the general fractional calculus (GFC) is proposed as a generalization of the Riesz fractional calculus, which was suggested by Marsel Riesz in 1949.

On Differential Subordination and Superordination for Univalent Function Involving New Operator

open access: yesIraqi Journal for Computer Science and Mathematics, 2022
The goal of this paper is to investigate some of the features of differential subordination of analytic univalent functions in an open unit disc. In addition, it has shed light on geometric features such as coefficient inequality, Hadamard product ...

On Solvability of the Sonin–Abel Equation in the Weighted Lebesgue Space

open access: yesFractal and Fractional, 2021
In this paper we present a method of studying a convolution operator under the Sonin conditions imposed on the kernel. The particular case of the Sonin kernel is a kernel of the fractional integral Riemman–Liouville operator, other various types of the ...

Convolution Algebras: Relational Convolution, Generalised Modalities and Incidence Algebras [PDF]

open access: yesLogical Methods in Computer Science, 2021
Convolution is a ubiquitous operation in mathematics and computing. The Kripke semantics for substructural and interval logics motivates its study for quantale-valued functions relative to ternary relations. The resulting notion of relational convolution

Applications of Magnetohydrodynamic Couple Stress Fluid Flow between Two Parallel Plates with Three Different Kernels

open access: yesJournal of Function Spaces, 2021
In this paper, we investigate the implementations of newly introduced nonlocal differential operators as convolution of power law, exponential decay law, and the generalized Mittag-Leffler law with fractal derivative in fluid dynamics.

Banach algebras of pseudodifferential operators and their almost diagonalization [PDF]

open access: yes, 2007
We define new symbol classes for pseudodifferntial operators and investigate their pseudodifferential calculus. The symbol classes are parametrized by commutative convolution algebras.

Triebel--Lizorkin space estimates for multilinear operators of sublinear operators [PDF]

open access: yes, 2003
In this paper, we obtain the continuity for some multilinear operators related to certain non-convolution operators on the Triebel--Lizorkin space. The operators include Littlewood--Paley operator and Marcinkiewicz operator.Comment: 15 pages, no figures,
