Almost Periodic Solution of A Discrete Lasota-Wazweska Model with Multiple Time-varying Delays
摘要
Abstract
An almost periodic discrete Lasota-Wazweska model with multiple time-varying delays is considered.The permanence of the system is obtained by applying the difference inequalities.And then,by using contraction mapping fixed point theorem and constructing a suitable Lyapunov functional,some sufficient conditions for the existence and the exponential convergence of the almost periodic positive solution are obtained.Moreover,an example and its numerical simulation are given to illustrate the feasibility of the main results.关键词
