Almost Periodic Solution of a Discrete Commensalism System [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2015
A nonautonomous discrete two-species Lotka-Volterra commensalism system with delays is considered in this paper. Based on the discrete comparison theorem, the permanence of the system is obtained. Then, by constructing a new discrete Lyapunov functional,

Almost Periodic Solution for Memristive Neural Networks with Time-Varying Delays [PDF]

open access: yesJournal of Applied Mathematics, 2013
This paper is concerned with the dynamical stability analysis for almost periodic solution of memristive neural networks with time-varying delays. Under the framework of Filippov solutions, by applying the inequality analysis techniques, the existence ...

Almost periodic skew-symmetric differential systems [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
We analyse solutions of almost periodic skew-symmetric homogeneous linear differential systems. We prove that in any neighbourhood of such a system there exists an almost periodic skew-symmetric system which does not possess any non-trivial almost ...

Almost periodic solutions of Volterra difference systems [PDF]

open access: yesDemonstratio Mathematica, 2017
We study the existence of an almost periodic solution of discrete Volterra systems by means of fixed point theory. Using discrete variant of exponential dichotomy, we provide sufficient conditions for the existence of an almost periodic solution.

$C^n$-almost periodic and almost periodic solutions for some nonlinear integral equations [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
In this paper, we investigate the existence of $C^n$-almost periodic solution for a class of nonlinear Fredholm integral equations, and the existence of almost periodic solution for a class of nonlinear functional integral equations.

Global Analysis of Almost Periodic Solution of a Discrete Multispecies Mutualism System [PDF]

open access: yesJournal of Applied Mathematics, 2014
This paper discusses a discrete multispecies Lotka-Volterra mutualism system. We first obtain the permanence of the system. Assuming that the coefficients in the system are almost periodic sequences, we obtain the sufficient conditions for the existence ...

Almost periodic solutions of neutral functional differential equations with Stepanov-almost periodic terms [PDF]

open access: yesElectronic Journal of Differential Equations, 2011
In this paper we study the existence of almost periodic solutions of an autonomous neutral functional differential equation with Stepanov-almost periodic terms in a Banach space.

Remotely $c$-almost periodic type functions in ${\mathbb{R}}^{n}$ [PDF]

open access: yes, 2022
summary:In this paper, we relate the notions of remote almost periodicity and quasi-asymptotical almost periodicity; in actual fact, we observe that a remotely almost periodic function is nothing else but a bounded, uniformly continuous quasi ...
