Published in 2024 at "Mathematische Nachrichten"

DOI: 10.1002/mana.202400184

Abstract: We study a superlinear elliptic boundary value problem involving the p$p$ ‐Laplacian operator, with changing sign weights. The problem has positive solutions bifurcating from the trivial solution set at the two principal eigenvalues of the… read more here.

Published in 2020 at "Ricerche Di Matematica"

DOI: 10.1007/s11587-020-00532-6

Abstract: We use a variational approach to study existence and regularity of solutions for a Neumann p-Laplacian problem with a reaction term on metric spaces equipped with a doubling measure and supporting a Poincare inequality. Trace… read more here.

Published in 2022 at "Symmetry"

DOI: 10.3390/sym14122486

Abstract: In this paper, we consider the following class of the fractional p&q-Laplacian problem: (−Δ)psu+(−Δ)qsu+V(x)(|u|p−2u+|u|q−2u)+g(x)|u|r−2u=K(x)f(x,u)+h(u),x∈RN,V:RN→R+ is a potential function, and h:R→R is a perturbation term. We studied two cases: if f(x,u) is sublinear, by means of… read more here.
