A generalised Nehari manifold method for a class of non-linear Schrödinger systems in ℝ3

AIP Conference Proceedings, 2022
We study the existence of positive solutions of a particular elliptic system in R3 composed of two non linear stationary Schrödinger equations (NLSEs), that is -∈2Δu + V(x)u = hv(u, v), -∈2Δv + V(x)v = hu(u, v). Under certain hypotheses on the potential V and the non linearity h, we manage to prove that there exists a solution (u∈, v∈) that decays ...

Nehari manifold and bifurcation for a ψ‐Hilfer fractional p‐Laplacian

Mathematical Methods in the Applied Sciences, 2021
In this paper, we discuss the bifurcation from infinity for nonlinear problem with a fractional p‐Laplacian in ψ‐fractional space , whose bifurcation is directly linked to the signal with 1 < q < p − 1.
