Presentation Name: A new construction of pseudo-Anosov homeomorphisms
Presenter: Professor John Hubbard
Date: 2018-10-22
Location: 上海数学中心220星空(中国)大厅
Abstract:

 I have a description of all pseudo-Anosov homeomorphisms that fix singularities and leaves emanating from them) in terms of something we call “ordered block permutations”.   It has allowed us to list the first 7000 or so such pseudoAnosov homeomorphisms, showing in particular that only about 10% fail to have totally real dilatations.
