Existence results for double phase problems depending on Robin and Steklov eigenvalues for the -Laplacian
Said El Manouni, Greta Marino, Patrick Winkert
In this paper we study double phase problems with nonlinear boundary condition and gradient dependence. Under quite general assumptions we prove existence results for such problems…
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…
Sign changing solution for a double phase problem with nonlinear boundary condition via the Nehari manifold
Leszek Gasinski, Patrick Winkert
In this paper we study quasilinear elliptic equations driven by the so-called double phase operator and with a nonlinear boundary condition. Due to the lack of regularity, we prove…
