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 Teichmüller space of isotopy classes of complex structures with real first Chern class zero and nonempty Kähler cone.

复杂的结构,矩图和Ricci形式

Ricci形式是一个矩图,用于表示一组精确的体积保留微分形在几乎复杂的结构空间上的作用。该观察结果为具有真正的第一Chern类零和非空Kähler锥的复杂结构的同位素类的Teichmüller空间上的Weil-Petersson辛形式提供了一种新方法。
