Abstract

In this talk, I will present our recent results (arXiv:2505.00638) on supersymmetric solutions in higher-derivative N=3 and N=4 supergravity within the conformal supergravity framework. We find a sharp contrast with the N=2 case: while N=2 admits both AdS2 × S2 and Minkowski vacua, N=3 and N=4 allow only Minkowski space as fully supersymmetric. I will explain the origin of this restriction and its implications for extended supergravity theories.
