Topology Seminar: Keiko Kawamuro
Topic
Open book foliation and fractional Dehn twist coefficient
Speakers
Details
This is joint work with Tetsuya Ito. Fractional Dehn twist coefficient (FDTC), defined by Honda-Kazez-Matic, is an invariant of mapping classes. In this talk we study FDTC by using open book foliation method, then obtain results in topology, geometry, and contact geometry of the open-book-manifold of a mapping class.
