Place: Conference Room A304, Department of Mathematical Sciences


Abstract: We introduce the notions of homology and homotopy for digraphs (directed graphs) and present their basic properties. In particular, homology groups are homotopy invariant, and the first homology group is abelization of the fundamental group.
