On the number of commensurable fibrations on a hyperbolic 3-manifold
arXiv:1403.0680
Abstract
By a work of Thurston, it is known that if a hyperbolic fibred -manifold has Betti number greater than 1, then admits infinitely many distinct fibrations. For any fibration on a hyperbolic -manifold , the number of fibrations on that are commensurable in the sense of Calegari-Sun-Wang to is known to be finite. In this paper, we prove that the number can be arbitrarily large.
