Quasilinear problems without the Ambrosetti-Rabinowitz condition
Anna Maria Candela, Genni Fragnelli, Dimitri Mugnai
We show the existence of nontrivial solutions for a class of highly quasilinear problems in which the governing operators depend on the unknown function. By using a suitable variat…

Controllability for a degenerate cascade system
Idriss Boutaayamou, Genni Fragnelli
In this paper we consider a cascade system in non divergence form which models the interaction between two different species, the first one can be seen as a predator and the other…

Controllability for a population equation with interior degeneracy
Genni Fragnelli
We deal with a degenerate model in divergence form describing the dynamics of a population depending on time, on age and on space. We assume that the degeneracy occurs in the inter…
