TITLE | Existence and non-existence of global surfaces of section |
ABSTRACT | More than a hundred years ago, Poincare and Birkhoff introduced the concept of a global surface of section, a powerful tool to discretize flows. There have been many applications, but there are not so many tools to construct these remarkable objects. We will describe some methods to prove their existence as well as their non-existence in various settings. |
