Semidefinite Invariant Subspaces: Degenerate Inner Products
Christian Mehl, André C. M. Ran, Leiba Rodman · Birkhäuser Basel eBooks · 2004
The paper concerns several classes of matrices in possibly degenerate indefinite inner products, such as expansive, dissipative, normal and plus matrices. The main results concern existence of invariant maximal semidefinite subspaces for matrices in these classes. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
