SUMMARY:Special Colloquium
CLASS:PUBLIC
DESCRIPTION:JESSE PETERSON\, VANDERBILT UNIVERSITY\n\n\"AMENABILITY AND V
 ON NEUMANN ALGEBRAS\"\n\nAmenability for groups is a notion that was fir
 st introduced by von\nNeumann in 1929 in order to provide a conceptual ex
 planation for the\nBanach-Tarski paradox. The notion has since been export
 ed to many\ndifferent areas of mathematics and continues to hold a disti
 nguished\nposition in fields such as group theory\, ergodic\ntheory\, and
  operator algebras. For von Neumann algebras the\nnotion plays a funda
 mental role\, with the classification of amenable\nvon Neumann algebras
  by Connes and Haagerup being considered a\ntouchstone of the area. In 
 this talk\, I will give a survey of\namenability and von Neumann algebra
 s\, emphasizing my own\ncontributions related to von Neumann algebras asso
 ciated with lattices\nin Lie groups.\n\nMC 5501
