Relations are established for the general case, and counting formulae are given in several particular cases, including the union of several mutually disjoint complete graphs.展开更多

文摘In this paper, Betti numbers are evaluated for several classes of graphs whose complements are bipartite graphs. Relations are established for the general case, and counting formulae are given in several particular cases, including the union of several mutually disjoint complete graphs.
