This is an authored directed relation from the source endpoint to the target endpoint.
Combining Ricci and scalar curvature gives the Einstein tensor.
Apply a standard functorial or canonical construction whose output is not merely a reduct of the input and is not generally an equivalent presentation of the same object.

This is an authored directed relation from the source endpoint to the target endpoint.
The Einstein tensor, plus the cosmological term when included, forms the geometric side of Einstein’s equation.
A mathematical concept supplies part of the formal language, state space, representation, or analytic machinery used by a scientific or mathematical-physics concept. The source is the mathematical predecessor; this does not claim that physical content follows from mathematics alone.
