Abstract:

In this talk, I shall report about a recent paper in collaboration with N. Papageorgiou and A. Pudelko (Math. Annalen, 2022).This talk is concerned with the qualitative analysis of solutions for a nonlinear elliptic Dirichlet equation driven by a double phase operator and a Carathéodory (p-1)-linear reaction. I first develop a detailed spectral analysis of the double phase operator. Next, I shall apply the results of this analysis to prove existence and multiplicity properties for problems in which there is resonance asymptotically at infinity. Several perspectives are developed in the final part of this talk.
