摘要
本文主要利用拓扑度理论,在“jumpingnonlinearities”情形,给出周期边界问题.x″+f(x)x′+g(t,x)=0x(0)=x(2π),x′(0)=x′(2π){在共振情形解的存在性条件,从而推广了C.
Abstract In this paper,we uses topological degree to obtain a existence condition of periodic solutions for Liénard equation with Landesman-Lazer conditions for“jumping nonlinearities”,which generalized a recent result of C.fabry .
