Einstein's field equations hamugešhâ-ye meydân-e Einstein Fr.: équations de champ d'Einstein A system of ten non-linear → G is the → _{μν}Einstein tensor
(a function of the → metric tensor),
κ is a coupling constant
called the → Einstein gravitational constant, and
T is the → _{μν}energy-momentum tensor.
The field equations
mean that the curvature of space-time is due to the distribution of mass-energy in
space. A more general form of the field equations proposed by Einstein
is:
G,
where Λ is the → _{μν} + Λg_{μν} = - κT_{μν}cosmological constant.Named after Albert Einstein (1879-1955);
