论文摘要
我们表明，对于任何积极的整数$ n $，都存在Quiver $ Q $，其中$ O（n^2）$ dertices和$ o（n^2）$边缘，使得$ n $ vertices上的任何颤抖的Quiver都是Quiver突变的完整子，相当于$ Q $。我们将此陈述概括为偏斜矩阵，并获得其他相关的结果。特别是，我们表明，任何箭袋都是箭量突变的完整子征质，等效于颤动的图形。
We show that for any positive integer $n$, there exists a quiver $Q$ with $O(n^2)$ vertices and $O(n^2)$ edges such that any quiver on $n$ vertices is a full subquiver of a quiver mutation equivalent to $Q$. We generalize this statement to skew-symmetrizable matrices and obtain other related results. In particular, we show that any quiver is a full subquiver of a quiver mutation equivalent to a quiver of a plabic graph.
