Abstract
We study the existence of a class of nonlinear elliptic equation
with Neumann boundary condition, and obtain infinitely many nodal
solutions. The study of such a problem is based on the variational
methods and critical point theory. We prove the conclusion by
using the symmetric mountain-pass theorem under the Cerami condition.
