摘要
Let X be a space of dimension at most 1. Then, the fundamental group is isomorphic to a subgroup of the first Cech homotopy group based on finite open covers. Consequently, for a one-dimensional continuum X, the fundamental group is isomorphic to a subgroup of the first Cech homotopy group. (C) 1998 Elsevier Science B.V.
