On rationally connected varieties over C1 fields of characteristic 0

Abstract

We use birational geometry to show that the existence of rational points on proper rationally connected varieties over fields of characteristic $0$ is a consequence of the existence of rational points on terminal Fano varieties. We discuss several consequences of this result, especially in relation to the $C_1$-conjecture. We also provide evidence that supports the conjecture in dimension 3 for $C_1$ fields of characteristic $0$.
