The Hurewicz Theorem relates a topological space's homotopy groups to its homology groups, showing that for a simply connected space, the first nonvanishing homotopy group and the first nonvanishing homology group occur in the same dimension and are isomorphic there, with a corresponding map linking the two families of groups in every dimension. Named for Witold Hurewicz, it is a foundational bridge between algebraic topology's two principal families of invariants, homotopy and homology.

Entity-backed identity for the statement-form enum value this theorem already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The statement-form fact itself stays on the theorem unchanged.
