Asymmetric Robin boundary-value problems with p-Laplacian and indefinite potential

Salvatore A. Marano, Nikolaos S. Papageorgiou

Abstract:
Four nontrivial smooth solutions to a Robin boundary-value problem with p-Laplacian, indefinite potential, and asymmetric nonlinearity super-linear at infinity are obtained, all with sign information. The semilinear case is also investigated, producing a nonzero fifth solution. Our proofs use variational methods, truncation techniques, and Morse theory.
