    4. Chains and Contractions: the Proof of Proposition 10. To prove Proposition 10 we need some facts about particular chains under contractions. Suppose X is an abstract simplicial complex, {u,w} = 77 G S (X), and q is t

      2. Basic Definitions. We consider a set to be a collection of distinct objects. We denote the order of a set S by |S|. 0 denotes the empty set. An abstract simplicial complex is a nonempty finite set X of nonempty finit
