摘要

．从内型紧致对称空间出发，给出了无限族的紧致齐次空间，它们携带不变非平坦Bismut连接，且具有消失的Ricci张量。这些例子证明是4阶的广义对称空间，并且(直到覆盖)可以被实现为Bismut平面模型空间的最小子流形，即紧李群。这种构造推广了对称空间的标准卡坦嵌入。

Infinite families of homogeneous bismut ricci flat manifolds

. Starting from compact symmetric spaces of inner type, we provide inﬁnite families of compact homogeneous spaces carrying invariant non-ﬂat Bismut connections with vanishing Ricci tensor. These examples turn out to be generalized symmetric spaces of order 4 and (up to coverings) can be realized as minimal submanifolds of the Bismut ﬂat model spaces, namely compact Lie groups. This construction generalizes the standard Cartan embedding of symmetric spaces.
