Killing vector fields and the curvature tensor of a Riemannian manifold
Yu. G. Nikonorov South Mathematical Institute of VSC RAS, Vladikavkaz, Russia
Abstract:
We find a convenient expression for the value of the covariant curvature $4$-tensor of an arbitrary Riemannian manifold on a quadruple of its Killing vector fields. With its use, we in particular obtain a simple deduction of the well-known formula to calculate the sectional curvature of a homogeneous Riemannian space.
Key words:
Riemannian manifold, Killing vector field, homogeneous Riemannian space, curvature tensor, sectional curvature.
