Banach

In this paper we discuss some properties of M ( A), the multiplier algebra of a commutative BANACH algebra A, and obtain the following result: If A is a faithful commutative-algebra, then so is M ( A).

本文讨论了交换Banach代数A的乘子代数（A）的若干性质，并且得到了如下的结论：如果A是一个忠实交换的~代数，那么M（A）也是一个交换的~代数。

The realization theory of linear systems defined over a commutative Banach algebra W is studied. For the given strictly proper rational matrix function over W, using the matrix fraction description, the controllable and observable realizations have been constructed.
