On the regularity of geodesics in the space of Kähler metrics

arXiv:1611.02390 · doi:10.1007/s40818-017-0034-8

Abstract

We prove that any two Kahler potentials on a compact Kahler manifold can be connected by a geodesic segment of C^{1,1} regularity. This follows from an a priori interior real Hessian bound for solutions of the nondegenerate complex Monge-Ampere equation, which is independent of a positive lower bound for the right hand side.
