Simplicial Complexes of Graphs

From the reviews: "The subject of this book is the topology of graph complexes. A graph complex is a family of graphs ... which is closed under deletion of edges. ... Topological and enumerative properties of monotone graph properties such as matchings, forests, bipartite graphs, non-Hamiltonian graphs, not-k-connected graphs are discussed. ... Researchers, who find any of the stated problems intriguing, will be enticed to read the book." (Herman J. Servatius, Zentralblatt MATH, Vol. 1152, 2009)
