在这篇文章中,我们引入了一种路径复形,它可以看作是单纯复形概念的推广。考虑路径复形的主要动机来自有向图(有向图)。给出了有向图的路同调和上同调的一个新概念。
In this paper we introduce a path complex that can be regarded as a generalization of the notion of a simplicial complex. The main motivation for considering path complexes comes from directed graphs(digraphs). We obtain a new notion of the path homology and cohomology of a digraph.
