摘要 本文考虑非线性常微分方程组周期解的存在性,得到了周期解的Nagumo型先验估计,由此在一般性条件下证明了方程组至少有一个T-周期解, This paper is concerned with the existence of periodic solutions for a nonlinear system of ordinary differential equations. We obtain Nagumo type a priori bound for the periodic solutions and then by using this a priori bound prove the existence of at least one T-periodic solution under some general conditions.
