摘要
研究了半黎曼流形上曲率张量和Ricci曲率的性质 。
In this paper, we at first study properties for curvature tensors, Ricci curvature on the singly warped products on semi Riemannian manifolds. And then, we establish the whole formulas of the curvature tensor, Ricci curvature and scalar curvature on the singly and warped product on semi Riemannian manifolds.
