WebOne of the early successes of surgery theory was the fibering theorem of Browder and Levine [B-L], which gives criteria for when a smooth map f: M → S1 is homotopic to a submersion. Here M is assumed to be a connected closed, smooth manifold of dimension ≥ 6, and we also require f to induce an isomorphism of fundamental groups. WebHurewicz isomorphism theorem.
