e/Einstein space

Information
has gloss	eng: In differential geometry and mathematical physics, an Einstein manifold is a Riemannian or pseudo-Riemannian manifold whose Ricci tensor is proportional to the metric. They are named after Albert Einstein because this condition is equivalent to saying that the metric is a solution of the vacuum Einstein equations (with cosmological constant), although the dimension, as well as the signature, of the metric can be arbitrary, unlike the four dimensional Lorentzian manifolds usually studied in general relativity.

Meaning
German
has gloss	deu: Die Einsteinmannigfaltigkeit ist ein Begriff aus dem mathematischen Teilgebiet der Differentialgeometrie sowie aus der allgemeinen Relativitätstheorie. Es handelt sich um einen Spezialfall einer (pseudo-)riemannschen Mannigfaltigkeit und wurde nach dem Physiker Albert Einstein benannt.
