The Ehlers group is a mathematical concept used primarily in the field of differential geometry and general relativity. Specifically, it refers to a group of transformations that preserve certain structures in the context of spacetime symmetries. In general relativity, the Ehlers group is associated with the symmetry properties of solutions to Einstein's field equations, particularly in the study of stationary spacetimes.
