Parametric nonlinear resonant Robin problems
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a nonlinear Robin problem driven by the -Laplacian. In the reaction we have the competing effects of two nonlinearities. One term is parametric, strictly -sub…
Positive solutions for a class of singular Dirichlet problems
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a Dirichlet elliptic problem driven by the Laplacian with singular and superlinear nonlinearities. The singular term appears on the left-hand side while the superlinear…
Double-phase problems and a discontinuity property of the spectrum
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a nonlinear eigenvalue problem driven by the sum of and -Laplacian. We show that the problem has a continuous spectrum. Our result reveals a discontinuity proper…
Double phase transonic flow problems with variable growth: nonlinear patterns and stationary waves
Anouar Bahrouni, Vicenţiu D. Rădulescu, Dušan D. Repovš
In this paper we are concerned with a class of double phase energy functionals arising in the theory of transonic flows. Their main feature is that the associated Euler equation is…
Periodic solutions for implicit evolution inclusions
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a nonlinear implicit evolution inclusion driven by a nonlinear, nonmonotone, time-varying set-valued map and defined in the framework of an evolution triple of Hilbert…
Asymmetric Robin problems with indefinite potential and concave terms
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a parametric semilinear Robin problem driven by the Laplacian plus an indefinite and unbounded potential. In the reaction, we have the competing effects of a concave te…
