Multiple solutions to a Robin problem with indefinite weight and asymmetric reaction

Analysis of PDEs 2015-06-09 v1

Abstract

The existence of two nontrivial smooth solutions to a semilinear Robin problem with indefinite unbounded potential and asymmetric nonlinearity ff is established. Both crossing and resonance are allowed. A third nonzero solution exists provided ff is C1C^1. Proofs exploit variational methods, truncation techniques, and Morse theory.
