MULTIPLE SOLUTIONS FOR QUASILINEAR ELLIPTIC EQUATIONS WITH SIGN-CHANGING POTENTIAL.

In this article, we study the quasilinear elliptic equation ... where the potential V (x) and the nonlinearity g(x, u) are allowed to be signchanging. Under some suitable assumptions on V and g, we obtain the multiplicity of solutions by using minimax methods. [ABSTRACT FROM AUTHOR]
