A note on some generalized curvature tensor

Ryszard Deszcz, Małgorzata Głogowska, Marian Hotloś, Miroslava Petrović-Torgašev, Georges Zafindratafa

摘要:

对于任意的半黎曼流形(M,g),我们定义一个广义曲率张量为由给定流形的度量张量、Ricci张量及其平方构成的Kulkarni-Nomizu乘积的线性组合.这个张量与准爱因斯坦空间、Roter空间和一些Roter型空间密切相关。

英文摘要:

For any semi-Riemannian manifold (M,g) we define some generalized curvature tensor as a linear combination of Kulkarni-Nomizu products formed by the metric tensor, the Ricci tensor and its square of given manifold. That tensor is closely related to quasi-Einstein spaces, Roter spaces and some Roter type spaces.
