Lorentz group



The Lorentz group is the orthogonal group for an invariant bilinear form of signature (+++)(-+++\cdots), O(n,1)O(n,1).

In physics the theory of special relativity the Lorentz group acts canonically as the group of linear isometries of Minkowski spacetime preserving a chosen basepoint. This is called the action by Lorentz transformations.
