含零矩阵对的通有标准形

Generic canonical form of pairs of matrices with zeros

Tatyana N. Gaiduk, Vladimir V. Sergeichuk

摘要:

本文考虑一类m × p和m × q矩阵对,其中某些元素为零,其它元素为任意元素,关于变换(A,B)->(SAR,SBL),S,R,L为非奇异的.我们证明,几乎所有的这些对减少到相同的对(C,D)从这个家庭,除了对的任意条目是某个多项式的零。根据图的性质,用组合方法构造多项式和对(CD)。

英文摘要:

We consider a family of pairs of m-by-p and m-by-q matrices, in which some entries are required to be zero and the others are arbitrary, with respect to transformations (A,B)--> (SAR,SBL) with nonsingular S, R, L. We prove that almost all of these pairs reduce to the same pair (C, D) from this family, except for pairs whose arbitrary entries are zeros of a certain polynomial. The polynomial and the pair (C D) are constructed by a combinatorial method based on properties of a certain graph.
