Dynamics for a discrete competition and cooperation model of two enterprises with multiple delays and feedback controls

Open Mathematics, 2017
This paper is concerned with a competition and cooperation model of two enterprises with multiple delays and feedback controls. With the aid of the difference inequality theory, we have obtained some sufficient conditions which guarantee the permanence ...

Almost periodic solution of a discrete competitive system with delays and feedback controls

Open Mathematics, 2019
A discrete nonlinear almost periodic multispecies competitive system with delays and feedback controls is proposed and investigated. We obtain sufficient conditions to ensure the permanence of the system.

An equivalence between Schauder's fixed point theorem and periodic solutions in Banach spaces

Cid and Mawhin proved that Brouwer's fixed point theorem is equivalent to theexistence of periodic solutions for a suitable class of ordinary differential equations in \((\mathbb R^n)\).

Ambrosetti–Prodi Periodic Problem Under Local Coercivity Conditions

Advanced Nonlinear Studies, 2018
In this paper we focus on the periodic boundary value problem associated with the Liénard differential equation x′′+f⁢(x)⁢x′+g⁢(t,x)=s{x^{\prime\prime}+f(x)x^{\prime}+g(t,x)=s}, where s is a real parameter, f and g are continuous functions and g is T ...

Pseudo S-asymptotically Bloch type periodicity with applications to partial stochastic neutral evolution equations [PDF]

Arab Journal of Mathematical Sciences
PurposeThis paper introduces the concept of (µ, ν)-pseudo S-asymptotically Bloch type (ω, k)- periodic functions, aiming to extend the framework of periodicity in stochastic analysis and to investigate their role in neutral partial stochastic ...
