摘要

我们考虑了超图在图上的实现问题，前提是每个超图都是由恰好两个顶点具有奇数度的子图实现的。这个问题与循环双覆盖猜想有关。我们证明了检验实现的存在性在计算上是困难的。硬度在各种设置中得到证明：对于在所有图上、在简单图上以及在来自几个受限类的图上的实现。

Hypergraph Edge Representations with the Use of Homological Paths

We consider the problem of realization of hypergraphs on a graph provided each hyperedge is realized by a subgraph in which exactly two vertices have odd degree. This problem is related to Cycle Double Cover conjecture. We prove that checking the existence of realization is computationally hard. The hardness is proved in various settings: for realizations on all graphs, on simple graphs, and on graphs from several restricted classes.
