Speaker: Chung-Ming Pan - Institut de Mathématiques de Toulouse
This talk aims to introduce a pluripotential approach to study uniform a priori estimates of Kähler–Einstein (KE) metrics on families of Fano varieties. I will first recall basic tools in the pluripotential theory and the variational approach to complex Monge-Ampère equations. I will then define a notion of convergence of quasi-plurisubharmonic functions in families of normal varieties and extend several classical properties under this context. Last, I will explain how these elements help to obtain a purely analytic proof of the openness of existing singular KE metrics and a uniform $L^\infty$ estimate of KE potentials.
This is joint work with Antonio Trusiani.
