A multiplicity theorem for anisotropic Robin equations
Nikolaos S. Papageorgiou, Patrick Winkert
In this paper we consider an anisotropic Robin problem driven by the -Laplacian and a superlinear reaction. Applying variational tools along with truncation and comparison te…
Positive solutions for singular anisotropic -equations
Nikolaos S. Papageorgiou, Patrick Winkert
In this paper we consider a Dirichlet problem driven by an anisotropic -differential operator and a parametric reaction having the competing effects of a singular term and o…
An existence result for singular Finsler double phase problems
Csaba Farkas, Patrick Winkert
In this paper, we study a class of singular double phase problems defined on Minkowski spaces in terms of Finsler manifolds and with right-hand sides that allow a certain type of c…
Existence and nonexistence of positive solutions for singular (p,q)-equations with superdiffusive perturbation
Nikolaos S. Papageorgiou, Patrick Winkert
We consider a nonlinear Dirichlet problem driven by the -Laplacian and with a reaction which is parametric and exhibits the combined effects of a singular term and of a supe…
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…
Robin fractional problems with symmetric variable growth
Anouar Bahrouni, Vicentiu Radulescu, Patrick Winkert
In this paper we study the fractional p(., .)-Laplacian and we introduce the corresponding nonlocal conormal derivative for this operator. We prove basic properties of the correspo…
