题目:Nonautonomous (p,q)-equations and some perspectives
摘要:I shall report on some recent joint results with Tianxiang Gou, and Nikolaos Papageorgiou and Shuai Yuan. In the first part of my talk, I shall develop an exhaustive analysis for the nonautonomous (p,q)-eigenvalue problem with indefinite weight and lack of compactness. This analysis distinguishes between the cases where p<q or q<p. In the second part of my talk, I will discuss a nonlinear Dirichlet problem driven by a nonautonomous double-phase differential operator and with a reaction consisting of a strongly singular term plus a concave perturbation. The proofs combine the Nehari manifold method with energy estimates and related variational and topological arguments.
