Singular chains and the fundamental group

Manuel Rivera, Mahmoud Zeinalian

Research output: Contribution to journalArticlepeer-review


We show that the natural algebraic structure of the singular chains on a path-connected topological space determines the isomorphism class of the fundamental group functorially. Moreover, we describe a notion of weak equivalence for the relevant algebraic structure under which the isomorphism class of the fundamental group is preserved.
