摘要

我们证明了具有流的图的几个连接属性，并推广了关于图的连接的一些结果。这转化为通过某些正集的标度一的连通性属性。例如，流的集合以及奇数和偶数热带自旋曲线的集合。这些正集分别是热带曲线上除数根的模空间以及奇数和偶数热带自旋曲线的模空间的底层正集。

Linkage of graphs with flows

We prove several linkage properties of graphs with flows, generalizing some results on linkage of graphs. This translates in properties of connectedness through codimension one of certain posets. For example, the poset of flows and the posets of odd and even tropical spin curves. These posets are, respectively, the posets underlying the moduli space of roots of divisors on tropical curves and the moduli spaces of odd and even tropical spin curves.
