Abstract: I shall report on some results in a recent joint paper with Nikolaos Papageorgiou (National Technical University, Athens) and Jian Zhang (Hunan University of Technology and Business).
The classical Ambrosetti-Prodi problem considers perturbations of the linear Dirichlet Laplace operator by a nonlinear reaction whose derivative jumps over the principal eigenvalue of the operator.
In this talk, we develop a related analysis for parametric problems driven by the nonlinear Robin (p,q)-Laplace operator. Under hypotheses that cover both the (p-1)-linear and the (p-1)-superlinear case, we prove an optimal existence and multiplicity property of solutions, as well as a non-existence result.
