Resonant Robin problems driven by the ▫$p$▫-Laplacian plus an indefinite potentialPapageorgiou, Nikolaos S.

The reaction is resonant with respect to a variational eigenvalue. For the principal eigenvalue we assume strong resonance. Using variational tools and critical gropus we prove existence and multiplicity theorems.20182019-08-22 14:35:59Članek v reviji109121sl
