Abstract

We prove that if a non-Sasakian contact metric 3-$\tau$-$a$-manifold or contact metric 3-$H$-manifold is weakly Einstein, then it is locally isometric to a Lie group equipped with a left invariant contact metric structure.

一些弱爱因斯坦接触度量3流形

我们证明了如果一个非sasakian接触度量3-$\tau$-$a$-流形或接触度量3-$H$-流形是弱爱因斯坦的，那么它是局部等距于一个具有左不变接触度量结构的李群。
