In mathematical physics, Minkowski space or Minkowski spacetime(named after the mathematician Hermann Minkowski) is themathematical space setting in which Einstein's theory of special relativity is most conveniently formulated. In this setting the three ordinary dimensions of space are combined with a single dimension oftime to form a four-dimensional manifold for representing a spacetime.
In theoretical physics, Minkowski space is often contrasted withEuclidean space. While a Euclidean space has only spacelikedimensions, a Minkowski space also has one timelike dimension. Theisometry group of a Euclidean space is the Euclidean group and for a Minkowski space it is the Poincaré group.
