Positive periodic solutions to nonlinear second order petiosic boundary value problems
摘要
Abstract
Periodic boundary value problem was an important subject in the nonlinear analysis and had extensive applications in some practical problems. In this paper,we investigated the multiplicity of positive solutions to some nonlinear second order periodic boundary value problem by using the fixed point theorem of cone expansion and compression.By the aid of the Green function of a class of linear problem,we obtained some existence results of at least two positive periodic solutions to periodic boundary value problem.关键词
