Abstract

The purpose of this article is to study the strict convexity of the Mabuchi functional along a C1,1C^{1,1}-geodesic, with the aid of the ϵ\epsilon-geodesics. We proved the L2L^2-convergence of the fiberwise volume element of the ϵ\epsilon-geodesic. Moreover, the geodesic is proved to be uniformly fiberwise non-degenerate if the Mabuchi functional is ϵ\epsilon-affine.

Comments

We corrected some errors and typos, and added several remarks and more details to explain this paper. Moreover, the more complicated proof of the strong L^2-convergence of the fiberwise volume element of the epsilon geodesic has been moved to the Appendix, and only remain the simpler one in the main context
