Higher-dimensional contact manifolds with infinitely many Stein fillings
Takahiro Oba
For any integer , we construct an infinite family of Stein fillable contact -manifolds each of which admits infinitely many pairwise homotopy inequivalent Stein fi…

Planar Lefschetz fibrations and Stein structures with distinct Ozsvath-Szabo invariants on corks
Cagri Karakurt, Takahiro Oba, Takuya Ukida
Thanks to a result of Lisca and Matic and a refinement by Plamenevskaya, it is known that on a 4-manifold with boundary Stein structures with non-isomorphic Spinc structures induce…

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.
