复结构、矩映射和Ricci形式(扩展版)

Complex structures, moment maps, and the Ricci form (Extended Version)

Oscar Garcia-Prada, Dietmar Salamon, Samuel Trautwein

摘要:

Ricci形式是殆复结构空间上保体积正态射群作用的矩映射。这一观察结果给出了一种新的方法来研究具有实第一陈类零和非空Kahler锥的复结构的合痕类在Teichmuller空间上的Weil-Petersson辛形式。

英文摘要:

The Ricci form is a moment map for the action of the group of exact volume preserving diffeomorphisms on the space of almost complex structures. This observation yields a new approach to the Weil-Petersson symplectic form on the Teichmuller space of isotopy classes of complex structures with real first Chern class zero and nonempty Kahler cone.
