Stepanov-like pseudo almost periodic functions on time scales and applications to dynamic equations with delay

open access: yesOpen Mathematics, 2018
In this paper, we introduce the concept of Sp-pseudo almost periodicity on time scales and present some basic properties of it, including the translation invariance, uniqueness of decomposition, completeness and composition theorem.

Pseudo Almost Periodic Sequence Solutions of Discrete Time Cellular Neural Networks [PDF]

open access: yesNonlinear Analysis, 2009
In this paper we discuss the existence and uniqueness of a k-pseudo almost periodic sequence solutions of a discrete time neural network. We give several sufficient conditions for the exponential and global attractivity of the solution.

Existence of doubly-weighted pseudo almost periodic solutions to non-autonomous differential equations

open access: yesElectronic Journal of Differential Equations, 2011
First we show that if the doubly-weighted Bohr spectrum of an almost periodic function exists, then it is either empty or coincides with the Bohr spectrum of that function.

Pseudo-almost periodic solutions for first-order neutral differential equations

open access: yesAdvances in Difference Equations, 2018
In this paper, we study a class of first-order neutral differential equations with time-varying delays and coefficients. Employing the fixed point method and differential inequality techniques, easily verifiable delay-independent criteria are established

Weighted Pseudo Almost-Periodic Functions and Applications to Semilinear Evolution Equations [PDF]

open access: yesAbstract and Applied Analysis, 2012
We first give a solution to a key problem concerning the completeness of the space of weighted pseudo almost-periodic functions and then establish a new composition theorem with respect to these functions.

Pseudo almost periodic dynamical behaviors of hematopoiesis model

open access: yesUkrains’kyi Matematychnyi Zhurnal
UDC 517.929, 517.518 We present a hematopoiesis model with nonlinear harvesting terms.  By using the fixed-point theorem and constructing suitable Lyapunov functionals, we establish new sufficient criteria required to guarantee the existence and ...

Existence and uniqueness of pseudo almost periodic solutions for Lienard-type systems with delays

open access: yesElectronic Journal of Differential Equations, 2016
This article concerns Lienard-type systems with time-varying delays. By applying the theory of exponential dichotomies, the properties of pseudo almost periodic function, inequality analysis techniques, and contraction mapping principle, new criteria ...

Stepanov pseudo almost periodic functions and applications [PDF]

open access: yesMathematical Methods in the Applied Sciences, 2020
In this work, we present basic results and applications of Stepanov pseudo almost periodic functions with measure. Using only the continuity assumption, we prove a new composition result of $\mu$-pseudo almost periodic functions in Stepanov sense. Moreover, we present different applications to semilinear differential equations and inclusions in Banach ...
