线性矩阵问题的典范矩阵

Canonical matrices for linear matrix problems

Vladimir V. Sergeichuk

摘要:

我们考虑一个大类的矩阵问题,其中包括问题的分类任意系统的线性映射。对于这类矩阵问题,我们构造了Belitskii算法,它是Jordan标准形的推广,并研究了不可分解的标准m-by-n矩阵的集合C(m,n).考虑C(m,n)是m × n矩阵仿射空间中的一个子集,我们证明了C(m,n)对每一个(m,n)都由有限个点和直线组成,或者C(m,n)对某个(m,n)包含一个二维平面.

英文摘要:

We consider a large class of matrix problems, which includes the problem of classifying arbitrary systems of linear mappings. For every matrix problem from this class, we construct Belitskii's algorithm for reducing a matrix to a canonical form, which is the generalization of the Jordan normal form, and study the set C(m,n) of indecomposable canonical m-by-n matrices. Considering C(m,n) as a subset in the affine space of m-by-n matrices, we prove that either C(m,n) consists of a finite number of points and straight lines for every (m,n), or C(m,n) contains a 2-dimensional plane for a certain (m,n).
