Perturbations of nonlinear eigenvalue problems
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider perturbations of nonlinear eigenvalue problems driven by a nonhomogeneous differential operator plus an indefinite potential. We consider both sublinear and superlinear…
Double phase problems with variable growth
Matija Cencelj, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a class of double phase variational integrals driven by nonhomogeneous potentials. We study the associated Euler equation and we highlight the existence of two differen…
Stability and instability properties of rotating Bose-Einstein condensates
Jack Arbunich, Irina Nenciu, Christof Sparber
We consider the mean-field dynamics of Bose-Einstein condensates in rotating harmonic traps and establish several stability and instability properties for the corresponding solutio…
-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…
Global and blow-up radial solutions for quasilinear elliptic systems arising in the study of viscous, heat conducting fluids
Marius Ghergu, Jacques Giacomoni, Gurpreet Singh
We study positive radial solutions of quasilinear elliptic systems with a gradient term in the form $$ \left\{ \begin{aligned} Δ_{p} u&=v^{m}|\nabla u|^α&&\quad\mbox{ in }Ω,\\ Δ_{p…
