Decomposition Theory in the Teaching of Elementary Linear Algebra.

Peer reviewed

London, R. R.; Rogosinski, H. P. – American Mathematical Monthly, 1990

Described is a decomposition theory from which the Cayley-Hamilton theorem, the diagonalizability of complex square matrices, and functional calculus can be developed. The theory and its applications are based on elementary polynomial algebra. (KR)
