确定量子矩阵素理想生成集的图论方法
A Graph Theoretic Method for Determining Generating Sets of Prime Ideals in Quantum Matrices
摘要：
我们采用图论的方法来寻找那些在环面作用下不变的$\mathcal{O}_q(\mathcal{M}_{m,n}(\mathbb{K}))$的素理想（$\mathbb{K}^*)^{m+n}$）的生成元。Launois \cite{launois3}表明，发电机组成的某些量子未成年人的矩阵规范发电机的$\mathcal{O}_q(\mathcal{M}_{m,n}(\mathbb{K}))$和在\cite{launois2}给出了一个算法来找到他们。本文修正了Lindström \cite{lind}和Gessel-Viennot~ \cite{gv}的一个经典结果，证明了量子子在特定理想的生成集中当且仅当我们能在关联的有向图中找到一组特定的顶点不相交有向路.
英文摘要：
We take a graph theoretic approach to the problem of finding generators for those prime ideals of $\mathcal{O}_q(\mathcal{M}_{m,n}(\mathbb{K}))$ which are invariant under the torus action ($\mathbb{K}^*)^{m+n}$. Launois \cite{launois3} has shown that the generators consist of certain quantum minors of the matrix of canonical generators of $\mathcal{O}_q(\mathcal{M}_{m,n}(\mathbb{K}))$ and in \cite{launois2} gives an algorithm to find them. In this paper we modify a classic result of Lindström \cite{lind} and Gessel-Viennot~\cite{gv} to show that a quantum minor is in the generating set for a particular ideal if and only if we can find a particular set of vertex-disjoint directed paths in an associated directed graph.
