In the theory of [[general relativity]], a '''stress–energy–momentum pseudotensor'''
This tensor allows the definition of [[energy–momentum]] system of the gravitating matter. In particular it allows the total of matter plus the gravitating energy–momentum to form a ''[[conserved current]]'' within the framework of [[general relativity]], so that the total energy–momentum crossing the [[hypersurface]] (3dimensional boundary) of any compact [[space–time]] [[hypervolume]] (4dimensional submanifold) ends up vanishing.
Some people (such as [[Erwin Schrödinger]]{{citation neededdate=October 2015}}) have objected to this derivation on the grounds that [[pseudotensor]]s are inappropriate objects in general relativity, but the conservation law only requires the use of the 4[[divergence]] of a pseudotensor which is, in this case, a tensor (which also vanishes). Also, most pseudotensors are sections of [[jet bundle]]s, which are now recognized as perfectly valid objects in GR.
