Positive solutions for the fractional Schrödinger equations with logarithmic and critical non‐linearities

open access: yesTransactions of the London Mathematical Society, Volume 8, Issue 1, Page 206-242, December 2021., 2021
Abstract In this paper, we study a class of fractional Schrödinger equations involving logarithmic and critical non‐linearities on an unbounded domain, and show that such an equation with positive or sign‐changing weight potentials admits at least one positive ground state solution and the associated energy is positive (or negative).

open access: yesMoroccan Journal of Pure and Applied Analysis, 2023
We investigate the existence of non-trivial weak solutions for the following p(x)-Kirchhoff bi-nonlocal elliptic problem driven by both p(x)-Laplacian and p(x)-Biharmonic operators {M(σ)(Δp(x)2u-Δp(x)u)=λϑ(x)|u|q(x)-2u(∫Ωϑ(x)q(x)|u|q(x)dx)r in Ω,u∈W2,p(.)
