The Mabuchi Geometry of Finite Energy Classes

Abstract

We introduce different Finsler metrics on the space of smooth Kähler potentials that will induce a natural geometry on various finite energy classes ${\mathcal{E}}_{\tilde{\chi }}(X,\omega )$. Motivated by questions raised by R. Berman, V. Guedj and Y. Rubinstein, we characterize the underlying topology of these spaces in terms of convergence in energy and give applications of our results to existence of Kähler-Einstein metrics on Fano manifolds.
