Journal of Systems Science and Complexity ( IF 2.1 ) Pub Date : 2021-06-28 , DOI: 10.1007/s11424-021-9330-1 Jian Pan , Baoxin Shang , Zhe Li , Shugong Zhang
In this paper, for a zero-dimensional polynomial ideal I, the authors prove that k[x1, x2, ⋯, xn]/I is cyclic if and only if the breadth of I is 0 or 1. Furthermore, the authors present a new algorithm to compute polynomial univariate representation (PUR) of such an ideal.

计算宽度至多为 1 的零维理想的 PUR
在本文中,对于零维多项式理想I,作者证明k [ x 1 , x 2 ,⋯, x n ]/ I是循环的当且仅当I的宽度为 0 或 1。此外,作者提出了一种新算法来计算这种理想的多项式单变量表示 (PUR)。
