除环K上的Ore扩张K[t;S,D]中的多项式f(t)是Wedderburn多项式,如果f(t)是幺半群且是K的代数子集的极小多项式.这些多项式已在[LL 5]中进行了研究。本文在一般的(S,D)-伪线性变换下,继续这一研究,并给出除环上矩阵的三角剖分、对角化和特征值的一些应用。在最后一节中,我们介绍和研究的概念,G-代数集,特别是允许推广韦德伯恩定理相对于因式分解的中心多项式。
A polynomial f(t) in an Ore extension K[t;S,D] over a division ring K is a Wedderburn polynomial if f(t) is monic and is the minimal polynomial of an algebraic subset of K. These polynomials have been studied in [LL5]. In this paper, we continue this study and give some applications to triangulation, diagonalization and eigenvalues of matrices over a division ring in the general setting of (S,D)-pseudo-linear transformations. In the last section we introduce and study the notion of G-algebraic sets which, in particular, permits generalization of Wedderburn’s theorem relative to factorization of central polynomials.
