Hideki Miyachi spoke in the Queens College Mathematics Colloquium on November 5, 2009.
Title: Introduction to the Teichmüller theory
Abstract: In this talk, I will introduce you to the Teichmüller theory. After fixing notations briefly, I will explain what is the quasiconformal deformation, and what is the Teichmüller equivalence. After then, I will give the definition and properties of asymptotic Teichmüller spaces. If time permits, I will survey my recent results on asymptotic Teichmüller spaces.
