由条件独立陈述产生的理想的极小素

Minimal primes of ideals arising from conditional independence statements

Irena Swanson, Amelia Taylor

摘要:

我们考虑在条件独立模型的背景下产生的理想,这些模型以不同于Herzog-Hibi-Hreinsdottir-Kahle-Rauh [13]和Ay-Rauh [1]的推广的方式推广了Fink [7]考虑的理想类。我们引入可切换集给出了一个组合描述的最小素理想,并为某些类,我们描述的最小组件。我们讨论了许多可能的解释,我们研究的理想,包括作为2 \times 2未成年人的通用超矩阵。我们还介绍了一般超矩阵的对角单项命令的定义,我们计算了一些Groebner基地。

英文摘要:

We consider ideals arising in the context of conditional independence models that generalize the class of ideals considered by Fink [7] in a way distinct from the generalizations of Herzog-Hibi-Hreinsdottir-Kahle-Rauh [13] and Ay-Rauh [1]. We introduce switchable sets to give a combinatorial description of the minimal prime ideals, and for some classes we describe the minimal components. We discuss many possible interpretations of the ideals we study, including as 2 \times 2 minors of generic hypermatrices. We also introduce a definition of diagonal monomial orders on generic hypermatrices and we compute some Groebner bases.
