Minimal number of singular fibers in a nonorientable Lefschetz fibration
Sinem Onaran, Burak Ozbagci
We show that there exists an admissible nonorientable genus Lefschetz fibration with only one singular fiber over a closed orientable surface of genus if and only if $g \ge…
Lefschetz fibrations on nonorientable 4-manifolds
Maggie Miller, Burak Ozbagci
Let be a nonorientable -dimensional handlebody without - and -handles. We show that admits a Lefschetz fibration over the -disk, whose regular fiber is a nonori…
On open books for nonorientable 3-manifolds
Burak Ozbagci
We show that the monodromy of Klassen's genus two open book for is the -homeomorphism of Lickorish, which is also known as the crosscap slide. Similarly, we sho…
Genus one Lefschetz fibrations on disk cotangent bundles of surfaces
Burak Ozbagci
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 decomposit…
Fillings of unit cotangent bundles of nonorientable surfaces
Youlin Li, Burak Ozbagci
We prove that any minimal weak symplectic filling of the canonical contact structure on the unit cotangent bundle of a nonorientable closed surface other than the real projective p…
Canonical contact unit cotangent bundle
Takahiro Oba, Burak Ozbagci
We describe an explicit open book decomposition adapted to the canonical contact structure on the unit cotangent bundle of a compact surface.
