与涡卷相关的Gorenstein二项式边理想
Gorenstein binomial edge ideals associated with scrolls
摘要:
设$I_G$是与顶点集[n]上的闭图$G$相关联的一般2 × n - Hankel矩阵上的二项式边理想.我们刻画了图$G$,其中$I_G$具有最大正则性,并且是Gorenstein图.
英文摘要:
Let $I_G$ be the binomial edge ideal on the generic 2 x n - Hankel matrix associated with a closed graph $G$ on the vertex set [n]. We characterize the graphs $G$ for which $I_G$ has maximal regularity and is Gorenstein.
