History-dependent operators and prox-regular sweeping processes [PDF]

open access: goldFixed Point Theory and Algorithms for Sciences and Engineering, 2022
We consider an abstract inclusion in a real Hilbert space, governed by an almost history-dependent operator and a time-dependent multimapping with prox-regular values.

Asymptotically regular operators in generalized Morrey spaces [PDF]

open access: greenBulletin of the London Mathematical Society, 2019
We obtain Calderón–Zygmund‐type estimates in generalized Morrey spaces Lq,φ(Ω) for nonlinear equations of p ‐Laplacian type. Our result is obtained under minimal regularity assumptions on both the operator and the domain Ω .

On the Quotients of Regular Operators

open access: yesUniversal Journal of Mathematics and Applications, 2019
We give some results about quotients of regular operators on Banach lattices by the linear span of the positive M-weakly and positive L-weakly compact operators.

Fredholm property of regular hypoelliptic operators on the scales of multianisotropic spaces [PDF]

open access: diamondITM Web of Conferences, 2022
This paper studies the Fredholm properties for a class of regular hypoelliptic operators. We establish necessary and sufficient conditions for a priori estimates for differential operators acting in multianisotropic Sobolev spaces in Rn.

Trace Operators on Regular Trees [PDF]

open access: yesAnalysis and Geometry in Metric Spaces, 2020
We consider different notions of boundary traces for functions in Sobolev spaces defined on regular trees and show that the almost everywhere existence of these traces is independent of the chosen definition of a trace.

Embedding operators and maximal regular differential-operator equations in Banach-valued function spaces

open access: goldJournal of Inequalities and Applications, 2005
This study focuses on anisotropic Sobolev type spaces associated with Banach spaces , . Several conditions are found that ensure the continuity and compactness of embedding operators that are optimal regular in these spaces in terms of interpolations of

Tensor products of approximation spaces associated with regular elliptic operators on compact manifolds

open access: diamondМатематичні Студії
The article describes the tensor products of approximation spaces associated with regular elliptic operators on tensor products of Lebesgue spaces $L_2(\partial\Omega)$, where  $\partial \Omega$ considers as smooth manifold that describes in the usual ...

On the solvability of the periodic problem for systems of linear functional differential equations with regular operators

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
Systems of two linear functional differential equations of the first order with regular operators are considered. General necessary and sufficient conditions for the unique solvability of the periodic problem are obtained.

Regular representations of vertex operator algebras, I [PDF]

open access: greenCommunications in Contemporary Mathematics, 1999
This paper is to establish a theory of regular representations for vertex operator algebras. In the paper, for a vertex operator algebra V and a V-module W, we construct, out of the dual space W*, a family of canonical weak V ⊗ V-modules [Formula: see text] with a nonzero complex number z as the parameter. We prove that for V-modules W, W1 and W2, a P(

A novel approach to graph distinction through GENEOs and permutants [PDF]

open access: yesScientific Reports
The theory of Group Equivariant Non-Expansive Operators (GENEOs) was initially developed in Topological Data Analysis for the geometric approximation of data observers, including their invariances and symmetries.
