Relative Kähler-Einstein metric on Kähler varieties of positive Kodaira dimension
Abstract
In this paper we introduce a new notion of canonical metric. The notion of generalized Kähler-Einstein metric on the Kähler varieties with an intermediate Kodaira dimension is not suitable and we need to replace the twisted Kähler-Einstein metric (KE) to new notion of Relative Kähler-Einstein metric (RKE) for such varieties and we highlight that to get C∞-solution of CMA equation of relative Kähler-Einstein metric we need Song-Tian-Tsuji measure (which has
minimal singularities with respect to other relative volume forms) be C∞-smooth and special fiber has canonical singularities. Moreover, we conjecture that if we have relative Kähler-Einstein metric then our family is stable in the sense of Alexeev,and Kollar-Shepherd-Barron
