Ethan Farber - Constructing pseudo-Anosovs from expanding interval maps
38th Annual Geometric Topology Workshop (Online), June 15-17, 2021 Ethan Farber, Boston College Title: Constructing pseudo-Anosovs from expanding interval maps Abstract: Pseudo-Anosov homeomorphisms of a surface are encoded by their action on a graph embedded in the surface. If this grap

Pseudo-Anosov Constructions and Penner's Conjecture - Balazs Strenner
Balazs Strenner November 12, 2015 https://www.math.ias.edu/seminars/abstract?event=83254 In this first talk, we give an introduction to Penner’s construction of pseudo-Anosov mapping classes. Penner conjectured that all pseudo-Anosov maps arise from this construction up to finite power.

C. Leininger - Teichmüller spaces and pseudo-Anosov homeomorphism (Part 3)
I will start by describing the Teichmuller space of a surface of finite type from the perspective of both hyperbolic and complex structures and the action of the mapping class group on it. Then I will describe Thurston's compactification of Teichmuller space, and state his classification

We discuss the problem of finding the minimal dilatation among pseudo-Anosov mapping classes on a fixed closed surface. In particular, for every nonorientable closed surface of even genus, we consider a simple candidate which conjecturally minimises the dilatation among pseudo-Anosov mappi
