Multiplicity of Periodic Solutions for Second Order Nonautonomous Differential Systems
摘要

We considered the periodic solutions for second order nonautonomous differential system with partially periodic potential and sublinear nonlinearity. Some sufficient conditions for the existence of multiple periodic solutions are obtained by using critical point theory.关键词
