Topological Moduli Spaces of Knots Allen Hatcher Classical knot theory is concerned with isotopy classes of knots in the 3 sphere, in other words, path-components of the space K of all smooth submanifolds of S 3 diffeomo

STABILIZATION FOR MAPPING CLASS GROUPS OF 3-MANIFOLDS ALLEN HATCHER AND NATHALIE WAHL Abstract. We prove that the homology of the mapping class group of any 3manifold stabilizes under connected sum and boundary connected

Spaces of Incompressible Surfaces Allen Hatcher The homotopy type of the space of PL homeomorphisms of a Haken 3 manifold was computed in [H1], and with the subsequent proof of the Smale conjecture in [H2], the computati

Diffeomorphism Groups of Reducible 3-Manifolds Allen Hatcher In a 1979 announcement by C´esar de S´a and Rourke [CR] there is a sketch of an intuitively appealing approach to measuring the difference between the homoto

Measured Lamination Spaces for 3-Manifolds Allen Hatcher One of Thurston’s important contributions to surface theory is his construction of measured lamination spaces. These spaces originally arose because their projec
