Optimal constant in an L² extension problem and a proof of a conjecture of Ohsawa

الأصل · EN

In this paper, we solve the optimal constant problem in the setting of Ohsawa's generalized L² extension theorem. As applications, we prove a conjecture of Ohsawa and the extended Suita conjecture, we also establish some relations between Bergman kernel and logarithmic capacity on compact and open Riemann surfaces.
