Location: Room 213, Richard Berry Building, The University of Melbourne

Abstract: Theorem: Every map from an n-manifold to the 2-sphere or 2-disk is homotopic to a broken fibration, and any two such are related by a simple set of moves. The talk will explain the terms in the theorem, give reasons why the theorem may be useful, describe its antecedents and relations to symplectic 4-manifolds, and maybe more.
