Methods of Algebraic Topology in Graph Theory. Homology theories.
Currently the problem of transferring results of algebraic topology to various categories of digraphs and graphs is widely investigated. The main technical tools are given by the homotopy theory and various homology theories. Now we present a collection of homology theories on various categories in graph theory. We describe main constructions and basic properties of these theories and describe relations between them. The examples which illustrate the computation of homology will be given.
