摘要
考虑具无穷时滞的非线性积分微分方程概周期的存在性和唯一性问题,利用矩阵测度和不动点方法获得了一类方程的概周期的存在性和唯一性的充分条件,推广了相应文献的结果.
The existence and uniqueness of periodic solutions of integro-different equations with infinite delay are considered. By combining the theory of matrix measure and the method of fixed point theorem, some sufficient conditions that guarantee the existence and uniqueness of periodic solution of the systems are obtained.
