摘要

摘要我们使用Courant对称群描述了广义Kähler结构的自然变形类，它确定了Kächler类和Kähner锥的概念到广义Köhler几何的自然扩展。我们证明了广义Kähler-Ricci流保留了这个广义的Kächler锥和下面的实泊松张量。

Deformation classes in generalized Kähler geometry

Abstract We describe natural deformation classes of generalized Kähler structures using the Courant symmetry group, which determine natural extensions of the notions of Kähler class and Kähler cone to generalized Kähler geometry. We show that the generalized Kähler-Ricci flow preserves this generalized Kähler cone, and the underlying real Poisson tensor.
