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 uniqueness of elliptic systems with double phase operators and convection terms
Greta Marino, Patrick Winkert
In this paper we study quasilinear elliptic systems driven by so-called double phase operators and nonlinear right-hand sides depending on the gradients of the solutions. Based on…
(p,q)-Equations with singular and concave convex nonlinearities
Nikolaos S. Papageorgiou, Patrick Winkert
We consider a nonlinear Dirichlet problem driven by the -Laplacian with . The reaction is parametric and exhibits the competing effects of a singular term and of conc…
-bounds for general singular elliptic equations with convection term
Greta Marino, Patrick Winkert
In this note we present -results for problems of the form in , in , on , where the growth condition for the function $B…
