Einstein field equation

Noun

 * 1)  A symmetric 4 &times; 4 tensor equation in general relativity in which the gravitational force is described as a curvature of spacetime caused by matter and energy.
 * The Einstein field equation states that the energy-momentum tensor is directly proportional to the Ricci tensor minus half of the Ricci scalar times the metric tensor plus the cosmological constant times the metric tensor.

Usage notes

 * A set of ten scalar equations equivalent to the tensor equation is referred as Einstein field equations.
