报告题目：Homology of graphs: a survey
报告简介：This is a literature review report on the homology of graphs. In 2013, Alexander Grigor'yan and Shing-Tung Yau et al. introduced a new notion - a path complex that can be regarded as a generalization of the notion of a simplicial complex. Moreover, we introduce the Betti numbers obtained from the various complex defined by graphs, and understand the relations among Algebra, Topology and Combination. Finally, we introduce a new cohomology theory recently proposed by Luigi Caputi et al., which is called multipath cohomology.
