Reference request: Representation Theory of Indefinite Orthogonal Lie Group and its Lie Algebra

364 Views Asked by At

In most textbooks, I have seen material on representation theory of the orthogonal group and its Lie algebra, and at most of the Lorentz group. However, I haven't seen any references talking about the representation theory of the general indefinite orthogonal group and its Lie algebra. Are there any such references at all?
