Existence of Normalized Solutions for Sobolev Critical Fractional Schrödinger–Poisson Systems

We study the existence of normalized solutions for fractional Schrödinger–Poisson systems with doubly critical growth. Under fairly general assumptions on $ f $ , with the aid of the Pohozaev manifold and the concentration-compactness principle, we show that there exists a normalized ground state solution for the fractional Schrödinger system when the prescribed mass $ m $ is sufficiently large.
