SUMMARY:Colloquium
CLASS:PUBLIC
DESCRIPTION:YVON VERBERNE\, WESTERN UNIVERSITY\n\n\"PSEUDO-ANOSOV HOMEOMORP
 HISMS\"\n\nThe mapping class group is the group of orientation preserving\
 nhomeomorphisms of a surface up to isotopy. In particular\, the mapping\nc
 lass group encodes information about the symmetries of a surface. The\nNie
 lsen-Thurston classification states that elements of the mapping\nclass gr
 oup are of one of three types: periodic\, reducible\, and\npseudo-Anosov. 
 In this talk\, we will focus our attention on the\npseudo-Anosov elements\
 , which are the elements of the mapping class\ngroup which mix the underly
 ing surface in a complicated way. In this\ntalk\, we will discuss both cla
 ssical and new results related to\npseudo-Anosov mapping classes\, as well
  as the connections to other\nareas of mathematics.\n\nMC 5501
