It is well known that matrices that are unitary with respect to a positive definite Hermitian form are all diagonalisable and have unit modulus eigenvalues. If the Hermitian form is indefinite then neither of these properties hold. In this talk I will show how to get around this. I will give geometrical applications to the isometries of real and complex hyperbolic space as well as anti de Sitter space.
