Open Books in Higher Dimensions
Chun-Sheng Hsueh (Berlin Mathematical School)
Abstract
We study open book decompositions on manifolds of dimension at least 4 using handle decompositions. We use handle moves to relate different open books on the same manifold and show that an open book with trivial monodromy can be alternatively constructed using a simple page and a non-trivial monodromy. As an application, we provide infinitely many examples in all dimensions at least 5 of diffeomorphic open books constructed using the same page but non-isotopic monodromy maps.
