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…

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…

Compact Sobolev embeddings on non-compact manifolds via orbit expansions of isometry groups

Csaba Farkas, Alexandru Kristály, Ágnes Mester

Given a complete non-compact Riemannian manifold with certain curvature restrictions, we introduce an expansion condition concerning a group of isometries of th…

Topological rigidity of compact manifolds supporting Sobolev-type inequalities

Csaba Farkas, Alexandru Kristály, Ágnes Mester

Let be an -dimensional compact Riemannian manifold with Ric. If supports an AB-type critical Sobolev inequality with Sobolev con…

On a critical Kirchhoff-type problem

Francesca Faraci, Csaba Farkas

In the present paper, we study a Kirchhoff type problem involving the critical Sobolev exponent. We give sufficient conditions for the sequentially weakly lower semicontinuity and…

On an open question of Ricceri concerning a Kirchhoff-type problem

Francesca Faraci, Csaba Farkas

In the present note we prove a multiplicity result for a Kirchhoff type problem involving a critical term, giving a partial positive answer to a problem raised by Ricceri.
