Braids, entropies and fibered 2-fold branched covers of 3-manifolds
Susumu Hirose, Eiko Kin
It is proved by Sakuma and Brooks that any closed orientable -manifold with a Heegaard splitting of genus admits a -fold branched cover that is a hyperbolic -manifold…

Volumes of fibered 2-fold branched covers of 3-manifolds
Susumu Hirose, Efstratia Kalfagianni, Eiko Kin
We prove that for any closed, connected, oriented 3-manifold M, there exists an infinite family of 2-fold branched covers of M that are hyperbolic 3-manifolds and surface bundles o…
