Real ,-Selfadjoint Matrices, be re-examined in this context. In particular, the reader will quickly verify that all the results and observations of Chapter 2 on the geometry of indefinite inner product spaces (when properly understood) are also valid for real spaces.

General Perturbations. Stability of Diagonalizable Matrices, of those cases in which analytic perturbations of .-selfadjoint matrices retain spectral properties which are familiar from the classical hermitian case is obtained. Analogous results for perturbations of .-unitary matrices are also discussed.
