Symmetries in General Relativity

Abstract:
Various symmetries have been defined by requiring the vanishing of the Lie derivative of different geometrical and physical objects in general relativity. These provide invariant bases for classification of the solutions of Einstein's field equations as well. Some of these symmetries and their mutual relationship have been discussed here.
