AI总结:

本文从多项式合冲或移动直线的新视角重新研究Toeplitz系统$T u =g$的求解,揭示了Toeplitz矩阵生成元与对应合冲模生成元之间的显式联系,并证明该模由两个$n$次元素生成,且解可表示为$g$的显式向量关于这两个生成元的余项。

摘要:

本文从新的视角重新研究Toeplitz系统$T u =g$的求解,通过将此类问题的解与多项式合冲或移动直线相关联。我们展示了Toeplitz矩阵的生成元与相应合冲模的生成元之间的显式联系。我们证明该模由两个$n$次元素生成,且$T u=g$的解可重新解释为依赖于$g$的显式向量关于这两个生成元的余项。

英文摘要:

In this paper, we re-investigate the resolution of Toeplitz systems $T u =g$, from a new point of view, by correlating the solution of such problems with syzygies of polynomials or moving lines. We show an explicit connection between the generators of a Toeplitz matrix and the generators of the corresponding module of syzygies. We show that this module is generated by two elements of degree $n$ and the solution of $T u=g$ can be reinterpreted as the remainder of an explicit vector depending on $g$, by these two generators.
