A note on gradient estimates for p-Laplacian equations
Umberto Guarnotta, Salvatore A. Marano
The aim of this short paper is to show that some assumptions in [10] can be relaxed and even dropped when looking for weak solutions instead of strong ones. This improvement is a c…
Continuous spectrum for a double-phase unbalanced growth eigenvalue problem
Laura Gambera, Umberto Guarnotta, Nikolaos S. Papageorgiou
We consider an eigenvalue problem for a double-phase differential operator with unbalanced growth. Using the Nehari method, we show that the problem has a continuous spectrum deter…
Existence, uniqueness, and decay results for singular -Laplacian systems in
Laura Gambera, Umberto Guarnotta
Existence of solutions to a -Laplacian singular system is obtained via shifting method and variational methods. A priori estimates are furnished through De Giorgi's technique, T…
