GENERALIZED TRANSLATION OPERATORS AND MARKOV PROCESSES

open access: yesDemonstratio Mathematica, 2001
Summary: We study the relationship between generalized translation operators and stochastic convolutions on locally compact spaces. We prove that stochastic convolution semigroups can generate Lévy type processes which are strong Markov Feller processes and, as an example, we study the Bingham convolution and its dual on integers.

Norm estimates for generalized translation operators associated with a singular differential operator

open access: yesProceedings of the Koninklijke Nederlandse Akademie Van Wetenschappen Series A, Indagationes Mathematicae, 1984
For many problems of harmonic analysis of eigenfunction expansions associated with a Sturm-Liouville equation it is indispensable to find an appropriate convolution structure. This can be achieved by introducing a generalized translation operator and by deriving suitable norm estimates.

Non-Markovian dynamics under time-translation symmetry

open access: yesPhysical Review Research, 2022
A dynamical symmetry is employed to determine the structure of the quantum non-Markovian time-local master equation. Such a structure is composed from two components: scalar kinetic coefficients and the standard quantum Markovian operator form.

Kinematic twist-three contributions to pseudo- and quasi-GPDs and translation invariance

open access: yesJournal of High Energy Physics, 2023
We present explicit expressions for the tree-level “kinematic” twist-three contributions to the nucleon matrix elements of gauge-invariant nonlocal quark-antiquark operators which can be used in lattice calculations of generalized parton distributions ...

Elliptic Equations with Arbitrarily Directed Translations in Half-Spaces

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2023
In this paper, we investigate the half-space Dirichlet problem for elliptic differential-difference equations with superpositions of differential operators and translation operators acting in arbitrary directions parallel to the boundary hyperplane.

Three-Way Decisions Based on Q-Rung Orthopair Fuzzy 2-Tuple Linguistic Sets with Generalized Maclaurin Symmetric Mean Operators

open access: yesMathematics, 2021
As a typical model of three-way decisions (3WD), decision-theoretic rough sets (DTRS), have gained attention from scholars in decision-making problems.

General Euler-Poisson-Darboux Equation and Hyperbolic B-Potentials

open access: yesСовременная математика: Фундаментальные направления, 2019
In this work, we develop the theory of hyperbolic equations with Bessel operators. We construct and invert hyperbolic potentials generated by multidimensional generalized translation. Chapter 1 contains necessary notation, definitions, auxiliary facts and

New sign uncertainty principles

open access: yesDiscrete Analysis, 2023
New sign uncertainty principles, Discrete Analysis 2023:9, 46 pp. The famous Heisenberg uncertainty principle is an inequality that states that the product of the variances of a function $f$ and its Fourier transform $\hat f$ is bounded below by an ...

Generalized weighted Besov spaces on the Bessel hypergroup

open access: yesJournal of Function Spaces and Applications, 2006
In this paper we study generalized weighted Besov type spaces on the Bessel-Kingman hypergroup. We give different characterizations of these spaces in terms of generalized convolution with a kind of smooth functions and by means of generalized ...
