A finiteness theorem for hyperbolic 3-manifolds
arXiv:0901.0300 · doi:10.1112/jlms/jdq106
Abstract
We prove that there are only finitely many closed hyperbolic 3-manifolds with injectivity radius and first eigenvalue of the Laplacian bounded below whose fundamental groups can be generated by a given number of elements. An application to arithmetic manifolds is also given.
