Abstract:

Based on the properties of the rank of the matrix polynomial, the necessary and sufficient conditions of generalized m involutory matrix and (m,l) idempotent matrix were obtained so as to generalize and improve the corresponding results  of m- involutory matrix and m-idempotent matrix.

Key words:  generalized m- involutory matrix; (m,l) idempotent matrix; rank of matrix; necessary and sufficient condition
