Mahler measures, Stable Pairs, and the Global coercive estimate for the Mabuchi Functional

Abstract

We show that the Mabuchi energy of any polarized manifold (X,L) is (bounded below) proper on the full space of Kahler metrics in the first Chern class of L if and only if (X,L) is asymptotically (semi)stable. In particular it now follows from work of Xiuxiong Chen and Jinguri Cheng that there exists a cscK metric in the first Chern class of L if and only if (X,L) is asymptotically stable, provided the reduced automorphism group of (X,L) is finite.
