Abstract:

By using the results about polynomial matrix in the system and control theory,this paper gives some discussions about the algebraic properties of polynomial matrices. The obtained main results include that the ringof n × n polynomial matrices is a principal ideal and principal one-sided ideal ring.

Key words: principal ideal ring, polynomial matrix, left (right) coprime
