Real Places and Surface Bundles
arXiv:1005.3856
Abstract
Our results complement D. Calegari's result that there are no hyperbolic once-punctured torus bundles over with trace field having real place. We exhibit several infinite families of pairs such that there exist hyperbolic surface bundles with over with fiber having punctures and Euler characteristic with trace field of having a real place. This supports our conjecture that there exist such examples for each pair with finitely many known exceptions.
