Zero-scalar curvature metric
This article defines a property that makes sense for a Riemannian metric over a differential manifold
This is the property of the following curvature being everywhere zero: scalar curvature
Definition
Symbol-free definition
A Riemannian metric on a differential manifold is said to be a zero-scalar curvature metric if the scalar curvature corresponding to this Riemannian metric is zero at all points.
