Sign-Changing Solutions for a Class of Nonlinear Elliptic Problems*

Abstract

In the present paper, the author studies the existence of sign-changing solutions for nonlinear elliptic equations, which have jumping nonlinearities, and may or may not be resonant with respect to Fučik spectrum, via linking methods under Cerami condition.
