This paper focuses on the study of the existence and nonexistence of radial solutions for the Schrödinger-Poisson system with doubly critical exponents Formula: see text under weaker assumptions. This work resolves an open problem proposed in the recent paper by Chen-Tang Commun. Pure Appl. Anal. 2024, and extends the results obtained by Yang-Wei Asymptotic Anal, 2026.
