Ricci curvature scalar

In mathematics, the scalar curvature of a surface is the familiar Gaussian curvature. For higher-dimensional manifolds, it is double of the sum of all the sectional curvatures along all the 2-planes spanned by some orthonormal frame. It is also the full trace of the Ricci curvature as well as of the curvature tensor.
