Abstract
In this paper, we discuss the Riemannian curvature tensor and the Riemannian- Christoel curvature tensor of a product Riemannian manifold. We show that the Riemannian curvature tensor and the Riemannian-Christoel curvature ten- sor of the product Riemannian manifold can be written respectively as the sum of the Riemannian curvature tensor and the Riemannian-Christoel curvature tensor of each Riemannian manifold. Furthermore, making use of these results some theorems regarding the local symmetry, satness and sectional curvature are given.
