DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NYC-NCG/116/
 ">The structure of KMS states for flows on an AF algebra</a>\nby Klaus Tho
 msen (Aarhus University) as part of Noncommutative geometry in NYC\n\n\nAb
 stract\nIn a recent work with George Elliott we have obtained a complete d
 escription of the configurations of KMS states that occur for flows on a u
 nital simple infinite dimensional AF algebra. The answer is that they all 
 do\, provided only that the simplex of 0-KMS states is affinely homeomorph
 ic to the tracial state space of the AF algebra\; a condition which is obv
 iously necessary. In the talk I will explain the road to this conclusion\,
  which can be seen as the culmination of work and ideas that go back more 
 than 40 years and has involved  very many mathematicians.\n
