摘要
本文利用Leray-Schauder型不动点定理和中立型算子的性质,我们证明了三阶变参数中立型奇性微分方程T-周期正解的存在性,其非线性项可以满足次线性、半线性和超线性条件。
By using the fixed point theorem of Leray-Schauder type and the properties of neutral operators, we prove that the existence of positive T-periodic solutions for a third-order neutral singular differen-tial equation with time-dependent parameter, the nonlinear term may satisfy sub-linearity, semi-linearity and super-linearity conditions.
