奇异矩阵的幂等分解

Decomposition of Singular Matrices into Idempotents

Adel Alahmadi, Surender Jain, André Leroy

摘要:

在本文中,我们提供了具体的结构的幂等代表典型的奇异矩阵在一个给定的环作为一个产品的幂等,并应用这些分解证明我们的主要结果。我们推广了Laffey(乘积幂等矩阵。线性多线性A. 1983)和Rao(乘积的幂等矩阵。Linear Algebra Appl.2009)到非交换设置,并填补了Rao主要定理的原始证明中的空白。我们还考虑了Bézout域上的奇异矩阵,当这样的矩阵是幂等矩阵的乘积。

英文摘要:

In this paper we provide concrete constructions of idempotents to represent typical singular matrices over a given ring as a product of idempotents and apply these factorizations for proving our main results. We generalize works due to Laffey (Products of idempotent matrices. Linear Multilinear A. 1983) and Rao (Products of idempotent matrices. Linear Algebra Appl. 2009) to noncommutative setting and fill in the gaps in the original proof of Rao's main theorems. We also consider singular matrices over Bézout domains as to when such a matrix is a product of idempotent matrices.
