Multi-dimensional (ω, c)-almost periodic type functions and applications
Nonautonomous Dynamical Systems, 2021 In this paper, we analyze various classes of multi-dimensional (ω, c)-almost periodic type functions with values in complex Banach spaces. The main structural properties and characterizations for the introduced classes of functions are presented.

On the connection between Sp-almost periodic functions defined on time scales and ℝ
Open Mathematics, 2022 It is well known that a sufficient and necessary condition for a continuous function gg to be almost periodic on time scale T{\mathbb{T}} is the existence of an almost periodic function ff on R{\mathbb{R}} such that ff is an extension of gg.

Semi-periodic solutions of difference and differential equations
Boundary Value Problems, 2012 The spaces of semi-periodic sequences and functions are examined in the relationship to the closely related notions of almost-periodicity, quasi-periodicity and periodicity.

c-Almost periodic type functions and applications
Nonautonomous Dynamical Systems, 2020 In this paper, we introduce several various classes of c-almost periodic type functions and their Stepanov generalizations, where c ∈ ℂ and |c| = 1. We also consider the corresponding classes of c-almost periodic type functions depending on two variables

Dynamic equation on time scale with almost periodic coefficients
Nonautonomous Dynamical Systems, 2020 In this paper, we discuss a nonautonomous dynamical equation on time scale in a Banach space. The nonautonomous case is particularly important and needs to be studied because it is frequently met in the mathematical models of evolutionary processes.

(ω, c)- Pseudo almost periodic distributions
Nonautonomous Dynamical Systems, 2020 The paper is a study of the (w, c) −pseudo almost periodicity in the setting of Sobolev-Schwartz distributions. We introduce the space of (w, c) −pseudo almost periodic distributions and give their principal properties.

Convolution on spaces of locally summable functions
Journal of Function Spaces, Volume 6, Issue 2, Page 187-203, 2008., 2008 In this work we prove the existence of convolution on Marcinkiewicz spaces 𝔐p(ℝ), 1 ≤ p < ∞, and, using pointwise approximate identities, we extend the classical definition of Hilbert transform to such spaces.

The Bessel‐Struve intertwining operator on ℂ and mean‐periodic functions
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 59, Page 3171-3185, 2004., 2004 We give a description of all transmutation operators from the Bessel‐Struve operator to the second‐derivative operator. Next we define and characterize the mean‐periodic functions on the space ℋ of entire functions and we characterize the continuous linear mappings from ℋ into itself which commute with Bessel‐Struve operator.

Diophantine approximations and almost periodic functions
Demonstratio Mathematica, 2017 In this paper we investigate the asymptotic behaviour of the classical continuous and unbounded almost periodic function in the Lebesgue measure.Using diophantine approximations we show that this function can be estimated by functions of polynomial type ...
