Measure Pseudo Almost Periodic Solutions of Shunting Inhibitory Cellular Neural Networks with Mixed Delays

Numerical Functional Analysis and Optimization, 2019
In this work, we consider a class of neutral shunting inhibitory cellular neural networks with mixed delays. We study the existence, uniqueness, and the exponential stability of the measure pseudo almost periodic (or μ-pseudo almost periodic) solutions ...

Calculus of fuzzy vector-valued functions and almost periodic fuzzy vector-valued functions on time scales

Fuzzy Sets Syst., 2019
In this paper, we establish an embedding theorem for the fuzzy multidimensional space and introduce the new types of multiplications of fuzzy vectors determined by the determinant algorithm.

Stability analysis of inertial neural networks: A case of almost anti‐periodic environment

Mathematical methods in the applied sciences, 2022
In this paper, a class of inertial neural networks with time delays is considered. By developing an approach based on differential inequality techniques coupled with Lyapunov function method, some assertions are demonstrated to guarantee the exponential ...

Almost periodic solutions for a class of non-instantaneous impulsive differential equations

Quaestiones Mathematicae. Journal of the South African Mathematical Society, 2018
This paper is concerned with almost periodic solutions for nonlinear non-instantaneous impulsive differential equations with variable structure. With the help of the notation of non-instantaneous impulsive Cauchy matrix, mild sufficient conditions are ...

Pseudo almost periodic solutions for some parabolic evolution equations with Stepanov-like pseudo almost periodic forcing terms

Journal of Mathematical Analysis and Applications, 2018
The aim of this work is to study the existence and uniqueness of μ-pseudo almost periodic solutions to a class of semilinear parabolic evolution equations with inhomogeneous boundary conditions, under the assumption that the forcing terms of the equation

Periodicity and Almost-Periodicity

2006
Periodicity and almost-periodicity are phenomena which play an important role in most branches of mathematics and in many other sciences. This is a survey paper1 on my work in this area and on related work. I restrict myself to periodicity questions in combinatorics on words (the main dish), but I start with a periodicity problem from number theory ...

Nonresonance Conditions for the Existence of Almost Periodic Solutions of Almost Periodic Systems

SIAM Journal on Applied Mathematics, 1971
For complex systems of the form \[ x' = Ax + \varepsilon g( {t,x,\varepsilon } ) , \] where A is a square matrix, g is analytic in the components of x and almost periodic in t, and $\varepsilon $ is a complex parameter, we give conditions on the Fourier exponents of g and the eigenvalues of A such that for $\| \varepsilon |$ sufficiently small, the ...
