Multiplicity of positive solutions for mixed local-nonlocal singular critical problems
No full textWe prove the existence of at least two positive weak solutions for mixed local-nonlocal singular and critical semilinear elliptic problems in the spirit of Hirano et al. (J Differ Equ 189(2):487–512, 2003), extending the recent results in Garain (J Geom Anal 33:212, 2023) concerning singular problems and, at the same time, the results in Biagi et al. (A Brezis–Nirenberg type result for mixed local and nonlocal operators, https://arxiv.org/abs/2209.07502, 2023) regarding critical problems
Necessary condition in a Brezis–Oswald-type problem for mixed local and nonlocal operators

Large sets at infinity and Maximum Principle on unbounded domains for a class of sub-elliptic operators
No full textMaximum Principles on unbounded domains play a crucial rôle in several problems related to linear second-order PDEs of elliptic and parabolic type. In this paper we consider a class of sub-elliptic operators L in RN and we establish some criteria for an unbounded open set to be a Maximum Principle set for L. We extend some classical results related to the Laplacian (by Deny, Hayman and Kennedy) and to the sub-Laplacians on stratified Lie groups (by Bonfiglioli and the second-named author)

Large sets at infinity and Maximum Principle on unbounded domains for a class of sub-elliptic operators
No full textMaximum Principles on unbounded domains play a crucial role in several problems related to linear second-order PDEs of elliptic and parabolic type. In the present notes, based on a joint work with prof. E. Lanconelli, we consider a class of sub-elliptic operators L in R^N and we establish some criteria for an unbounded open set to be a Maximum Principle set for L. We extend some classical results related to the Laplacian(proved by Deny, Hayman and Kennedy) and to the sub-Laplacians on homogeneous Carnot groups (proved by Bonfiglioli and Lanconelli)
