Title: Normalized solutions for fractional Schrodinger-Choquard systems with Sobolev critical coupled nonlinearity Authors: Zilin Chen (Jiangnan Univ., Wuxi, Jiangsu, China) Yang Yang (Jiangnan Univ., Wuxi, Jiangsu, China) Abstract: We study the existence of normalized solutions for a system of fractional Schrodinger-Choquard with Sobolev critical coupling term. We obtain the existence of the positive normalized ground state solution, and in a special case we obtain a mountain pass type normalized solution. Submitted March 11, 2025. Published May 13, 2025.
