Existence of infinitely many nodal solutions for a superlinear Neumann boundary value problem
Boundary Value Problems, 2005 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.
