Curvature Free Rigidity for Higher Rank Three-manifolds
نویسنده
چکیده
We prove two rigidity results for complete Riemannian threemanifolds of higher rank. Complete three-manifolds have higher spherical rank if and only if they are spherical space forms. Complete finite volume threemanifolds have higher hyperbolic rank if and only if they are finite volume hyperbolic space forms.

Quasi-conformal Rigidity of Negatively Curved Three Manifolds
In this paper we study the rigidity of infinite volume 3-manifolds with sectional curvature −b2 ≤ K ≤ −1 and finitely generated fundamental group. In-particular, we generalize the Sullivan’s quasiconformal rigidity for finitely generated fundamental group with empty dissipative set to negative variable curvature 3-manifolds. We also generalize the rigidity of Hamenstädt or more recently Besson-...
متن کاملPositive curvature and the elliptic genus
We prove some results about the vanishing of the elliptic genus on positively curved Spin manifolds with logarithmic symmetry rank. The proofs are based on the rigidity of the elliptic genus and Kennard’s improvement of the Connectedness Lemma for transversely intersecting, totally geodesic submanifolds.
متن کاملTits Alternative for Closed Real Analytic 4-manifolds of Nonpositive Curvature
We study subgroups of fundamental groups of real analytic closed 4-manifolds with nonpositive sectional curvature. In particular, we are interested in the following question: if a subgroup of the fundamental group is not virtually free abelian, does it contain a free group of rank two ? The technique involves the theory of general metric spaces of nonpositive curvature.
متن کاملConsequences of Ergodic Frame Flow for Rank Rigidity in Negative Curvature
This paper presents a rank rigidity result for negatively curved spaces. Let M be a compact manifold with negative sectional curvature and suppose that along every geodesic in M there is a parallel vector field making curvature −a with the geodesic direction. We prove that M has constant curvature equal to −a if M is odd dimensional, or if M is even dimensional and has sectional curvature pinch...
متن کاملFinite part of operator K-theory for groups finitely embeddable into Hilbert space and the degree of non-rigidity of manifolds
In this paper, we study lower bounds on the K-theory of the maximal C∗-algebra of a discrete group based on the amount of torsion it contains. We call this the finite part of the operator K-theory and give a lower bound that is valid for a large class of groups, called the “finitely embeddable groups”. The class of finitely embeddable groups includes all residually finite groups, amenable group...
