وجود و ثبات راه حل های مثبت تقریبا دوره ای برای یک سیستم رقابتی در مقیاس زمانی

This paper concerns with the asymptotic behaviors of an almost periodic competitive system on time scales. By employing time scale calculus theory and Lyapunov functional method, a good understanding of the existence and uniformly asymptotic stability of unique positive almost periodic solution of the system is obtained. Also, two examples together with their numerical simulations illustrate the feasibilities of our analytical results.
