Abstract

Our results complement D. Calegari's result that there are no hyperbolic once-punctured torus bundles over S1S^1 with trace field having real place. We exhibit several infinite families of pairs (χ,p)(-\chi, p) such that there exist hyperbolic surface bundles with over S1S^1 with fiber having pp punctures and Euler characteristic χ\chi with trace field of having a real place. This supports our conjecture that there exist such examples for each pair (χ,p)(-\chi, p) with finitely many known exceptions.
