Notes and References
Many books on numerical linear algebra or matrix analysis contain material on invariant subspaces, for example
- David S. Watkins. Fundamentals of Matrix Computations Third edition, Wiley, New York, USA, 2010.
The ultimate reference is perhaps the book by Gohberg, Lancaster, and Rodman, which has an accessible introduction but is mostly at the graduate textbook or research monograph level.
- Israel Gohberg, Peter Lancaster, and Leiba Rodman, Invariant Subspaces of Matrices with Applications, Society for Industrial and Applied Mathematics, Philadelphia, PA, USA, 2006 (unabridged republication of book first published by Wiley in 1986).
