Theinterval exchange map is a generalization of the irrational rotation.It has very interesting dynamical properties and deeply related withnumber theory and geometry.The dynamics of irrational rotation isdetermined by its rotation angle and the continued fraction algorithmis the main tool to deal with the rotation angle.The continuedfraction algorithm is generalized by Rauzy, Veech and Zorich to theinterval exchange maps.This induction algorithm is strongly relatedto Teichmuller flow of the moduli space of abelian differentials asthe usual continued fraction algorithm can be considered as thegeodesic flow of the modular space.In this lecture series, we willstudy the continued fracttion algorithm and suspension of theinterval exchage map and follow the big theorems like almosteverywhere unique ergodicity of the interval exchange map.
