摘要 通过变换和不动点定理,研究了一类非线性Lotka-Volterra系统的正概周期解的存在性,获得了新的结果. With the help of a substitution and applying the fixed point theorem, we derive a criterion of the existence of positive almost periodic solutions for a class of Lotka-Volterra type system.The main results improve and generalize the former results.
