Combined effects of singular and superlinear nonlinearities in singular double phase problems in
Wulong Liu, Patrick Winkert
This paper is concerned with multiplicity results for parametric singular double phase problems in via the Nehari manifold approach. It is shown that the problem und…
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…
Singular Finsler double phase problems with nonlinear boundary condition
Csaba Farkas, Alessio Fiscella, Patrick Winkert
In this paper we study a singular Finsler double phase problem with a nonlinear boundary condition and perturbations that have a type of critical growth, even on the boundary. Base…
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…
