关于矩阵有限决定性的一个注记

A note on finite determinacy of matrices

Thuy Huong Pham, Pedro Macias Marques

摘要:

本文给出了M中矩阵A是G-决定的一个充要条件,其中M是无限域上2 × 2矩阵的形式幂级数环,G是通过坐标变换和两边可逆矩阵相乘作用于M的群.

英文摘要:

In this note, we give a necessary and sufficient condition for a matrix A in M to be finitely G-determined, where M is the ring of 2 x 2 matrices whose entries are formal power series over an infinite field, and G is a group acting on M by change of coordinates together with multiplication by invertible matrices from both sides.
