On the J-flow in higher dimensions and the lower boundedness of the mabuchi energy

Abstract

The J-flow is a parabolic flow on Kähler manifolds. It was defined by Donaldson in the setting of moment maps and by Chen as the gradient flow of the J-functional appearing in his formula for the Mabuchi energy. It is shown here that under a certain con- dition on the initial data, the J-flow converges to a critical metric. This is a generalization to higher dimensions of the author’s previous work on Kähler surfaces. A corollary of this is the lower boundedness of the Mabuchi energy on Kähler classes satisfying a certain inequality when the first Chern class of the manifold is negative. © 2006 Journal of Differential Geometry.
