On dynamically convex contact manifolds and filtered symplectic homology
Myeonggi Kwon, Takahiro Oba
In this paper we are interested in characterizing the standard contact sphere in terms of dynamically convex contact manifolds which admit a Liouville filling with vanishing symple…

Symplectic submanifolds in dimension from hyperelliptic Lefschetz fibrations
Takahiro Oba
We provide a closed, simply connected, symplectic -manifold having infinitely many codimension symplectic submanifolds. These are mutually homologous but homotopy inequivale…
