Multiple and Sign-Changing Solutions for Boundary Value Problems of Second-Order Nonlinear Difference Equations
摘要
Abstract
In this paper,by using the method of invariant sets of descending flow and variational method,we establish sufficient conditions to obtain the existence of positive solutions,negative solutions and sign-changing solutions of a class of second-order nonlinear difference equation with Robin boundary condition.In addition,we use the relevant example to verify the feasibility of the theorem.关键词
