The sub-supersolution method for variable exponent double phase systems with nonlinear boundary conditions
Umberto Guarnotta, Roberto Livrea, Patrick Winkert
In this paper we study quasilinear elliptic systems driven by variable exponent double phase operators involving fully coupled right-hand sides and nonlinear boundary conditions. T…
Some recent results on singular p-Laplacian equations
Umberto Guarnotta, Roberto Livrea, Salvatore Angelo Marano
A short account of some recent existence, multiplicity, and uniqueness results for singular p-Laplacian problems either in bounded domains or in the whole space is performed, with…
Some recent results on singular p-laplacian systems
Umberto Guarnotta, Roberto Livrea, Salvatore A. Marano
Some recent existence, multiplicity, and uniqueness results for singular p-Laplacian systems either in bounded domains or in the whole space are presented, with a special attention…
Existence of two solutions for singular Φ-Laplacian problems
Pasquale Candito, Umberto Guarnotta, Roberto Livrea
Existence of two solutions to a parametric singular quasi-linear elliptic problem is proved. The equation is driven by the Φ-Laplacian operator and the reaction term can be non-mon…
