Descriptif
I will discuss a method that we recently introduced in collaboration with Chu and Weinkove which gives interior C1,1 estimates for the non-degenerate complex Monge-Ampère equation on compact Kähler manifolds (possibly with boundary). The method is sufficiently robust to also give C1,1 regularity of geodesic segments in the space of Kähler metrics (thus resolving a long-standing problem originating from the work of Chen), of quasi-psh envelopes in Kähler as well as nef and big classes (solving a conjecture of Berman), and of geodesic rays that arise from test configurations (improving results of Phong and Sturm), and it even applies to the almost-complex case.

BamlerRichard H.We present a new compactness theory of Ricci flows. This theory states that any sequence of Ricci flows that is pointed in an appropriate sense, subsequentially converges to a synthetic flow.
