Abstract:Abstract. Let A be either a simplicial complex K or a small category C with V (A) as its set of vertices or objects. We define a twisted structure on A with coefficients in a simplicial group G as a functionthere exists an edge in A joining v with w or an arrow either from v to w or from w to v. We give a canonical construction of twisted simplicial group as well as twisted homology for A with a given twisted structure. Also we determine the homotopy type of of this simplicial group as the loop space over cert… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
