多元(n-D)多项式矩阵分解是多维系统和信号处理中的基础研究问题。本文证明了多元矩阵分解现有结果的几种扩展。此外,借助最近发展起来的多元矩阵分解的一般理论,对二元多项式矩阵分解给出了新的证明。这种新方法还产生了用于一般二元矩阵分解的实际计算的递归算法,该算法依赖于模的 Gröbner 基的算法,并且不涉及函数域的计算。
Multivariate (n-D) polynomial matrix factorizations are basic research problems in multidimensional systems and signal processing. In this paper several extensions of the existing results on multivariate matrix factorizations are proved. Moreover, by means of the general theory of multivariate matrix factorizations recently developed, a new proof is given to the bivariate polynomial matrix factorizations. This new approach produces also a recursive algorithm for the actual computation of the general bivariate matrix factorizations, which relies on the algorithm of the Gröbner bases for modules and does not involve calculations over the function fields.
