Multiple nodal solutions to a Robin problem with sign-changing potential and locally defined reaction
U. Guarnotta, S. A. Marano, N. S. Papageorgiou
A Robin boundary-value problem with non-homogeneous differential operator, indefinite potential, and reaction defined only near zero is investigated. The existence of one or more n…
-equations asymmetric at both zero and infinity
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a -equation, that is, a nonlinear nonhomogeneous elliptic equation driven by the sum of a -Laplacian and a Laplacian with . The reaction term is -…
Double-phase problems with reaction of arbitrary growth
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a parametric nonlinear nonhomogeneous elliptic equation, driven by the sum of two differential operators having different structure. The associated energy functional ha…
Resonant Robin problems driven by the -Laplacian plus an indefinite potential
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a nonlinear Robin problems driven by the -Laplacian plus an indefinite potential. The reaction is resonant with respect to a variational eigenvalue. For the principa…
