Abstract
We classify pointed spaces according to the fundamental group of their reduced suspension. A pointed space is either of horseshoe type or has fundamental group isomorphic to that of a totally path disconnected space. Among totally path disconnected spaces, the fundamental group is shown to be a complete invariant for a notion of topological equivalence weaker than that of homeomorphism.
