Nodal solutions for the double phase problems
Chao Ji, Nikolaos S. Papageorgiou
We consider a parametric nonautonomous -equation with unbalanced growth as follows \begin{align*} \left\{ \begin{aligned} &-Δ_p^αu(z)-Δ_q u(z)=λ\vert u(z)\vert^{τ-2}u(z)+f(…
Anisotropic -equations with convex and negative concave terms
Nikolaos S. Papageorgiou, Dušan D. Repovš, Calogero Vetro
We consider a parametric Dirichlet problem driven by the anisotropic -Laplacian and with a reaction which exhibits the combined effects of a superlinear (convex) term and of…
Global multiplicity for parametric anisotropic Neumann -equations
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a Neumann boundary value problem driven by the anisotropic -Laplacian plus a parametric potential term. The reaction is ``superlinear". We prove a global (with r…
Positive solutions for the Robin -Laplacian plus an indefinite potential
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a nonlinear elliptic equation driven by the Robin -Laplacian plus an indefinite potential. In the reaction we have the competing effects of a strictly -sublin…
On a class of singular anisotropic -equations
Nikolaos S. Papageorgiou, Patrick Winkert
We consider a Dirichlet problem driven by the anisotropic -Laplacian and with a reaction that has the competing effects of a singular term and of a parametric superlinear pe…
Nonlinear singular problems with indefinite potential term
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a nonlinear Dirichlet problem driven by a nonhomogeneous differential operator plus an indefinite potential. In the reaction we have the competing effects of a singular…
