摘要:Let M be a compact, hyperbolizable 3-manifold with nonempty incompressible boundary and let AH(pi (1)(M)) denote the space of (conjugacy classes of) discrete faithful representations of pi (1)(M) into PSL2(C). The components of the interior MP(pi (1)(M)) of AH(pi (1)(M)) (as a subset of the appropriate representation variety) are enumerated by the space A(M) of marked homeomorphism types of oriented, compact, irreducible 3-manifolds homotopy equivalent to M. In this paper, we give a topologica...

摘要:For stationary harmonic maps between Riemannian manifolds, we provide a necessary and sufficient condition for the uniform interior and boundary gradient estimates in terms of the total energy of maps. We also show that if analytic target manifolds do not carry any harmonic S-2, then the singular sets of stationary maps are m less than or equal to n - 4 rectifiable. Both of these results follow from a general analysis on the defect measures and energy concentration sets associated with a weakl...

摘要:Thurston's ending lamination conjecture proposes that a finitely generated Kleinian group is uniquely determined (up to isometry) by the topology of its quotient and a list of invariants that describe the asymptotic geometry of its ends. We present a proof of this conjecture for punctured-torus groups. These are free two-generator Kleinian groups with parabolic commutator, which should be thought of as representations of the fundamental group of a punctured torus. As a consequence we verify th...

摘要:The mapping torus of an endomorphism Phi of a group G is the HNN-extension G*(G) with bonding maps the identity and Phi. We show that a mapping torus of an injective free group endomorphism has the property that its finitely generated subgroups are finitely presented and, moreover, these subgroups are of finite type.
