Cartan空间上的一个Kähler结构

A Kähler Structure on Cartan Spaces

E. Peyghan, A. Tayebi

摘要:

本文在Cartan流形上定义了一个新的度量,并得到了它们的余切丛上的一个Kähler结构.证明了在具有负常旗曲率的Cartan流形M上,(T* M_0,G,J)具有Käahlerian结构.对于具有正常旗曲率的Cartan流形,我们证明了零截面周围的管具有Käahlerian结构。最后通过计算Levi-Civita联络和与此度量有关的曲率分量,证明了不存在非Riemann Cartan结构使得(T* M_0,G,J)成为Einstein流形或局部对称流形。

英文摘要:

In this paper, we define a new metric on Cartan manifolds and obtain a Kähler structure on their cotangent bundles. We prove that on a Cartan manifold M of negative constant flag curvature, (T* M_0, G, J) has a Käahlerian structure. For Cartan manifolds of positive constant flag curvature, we show that the tube around the zero section has a Käahlerian structure. Finally by computing the Levi-Civita connection and components of curvature related to this metric, we show that there is no non- Riemannian Cartan structure such that (T* M_0, G, J) became a Einstein manifold or locally symmetric manifold.
