Query: Genus one Lefschetz fibrations on disk cotangent bundles of surfaces   We describe a Lefschetz fibration of genus one on the disk cotangent bundle
of any closed orientable surface S. As a corollary, we obtain an explicit genus
one open book decomposition adapted to the canonical contact structure on the
unit cotangent bundle of S.
