Global Stability of Positive Periodic Solutions and Almost Periodic Solutions for a Discrete Competitive System

open access: yesDiscrete Dynamics in Nature and Society, 2015
A discrete two-species competitive model is investigated. By using some preliminary lemmas and constructing a Lyapunov function, the existence and uniformly asymptotic stability of positive almost periodic solutions of the system are derived. In addition,

Almost Periodic (Type) Solutions to Parabolic Cauchy Inverse Problems

open access: yesAbstract and Applied Analysis, 2012
We first show the existence and uniqueness of (pseudo) almost periodic solutions of some types of parabolic equations. Then, we apply the results to a type of Cauchy parabolic inverse problems and show the existence, uniqueness, and stability.
