On the existence of normalized solutions to a class of fractional Choquard equation with potentials

Yongpeng Chen, Zhipeng Yang, Jianjun Zhang

This paper investigates the existence of normalized solutions to the nonlinear fractional Choquard equation: $$ (-Δ)^s u+V(x) u=λu+f(x)\left(I_α*\left(f|u|^q\right)\right)|u|^{q…

Normalized Solutions and Semiclassical Concentration for Upper-Critical Fractional Choquard Equations

Yergen Aikyn, Yongpeng Chen, Michael Ruzhansky +1

We study a fractional Choquard equation with an upper-critical Hartree term, an -supercritical Hartree perturbation, and a semiclassical potential under a prescribed -mas…
