Workshop on Geometric Group Theory

Mladen Bestvina (University of Utah)

  1. Limit groups intro – definitions, examples, nonexamples.
  2. What limit groups are good for; MR-diagrams; examples thereof.
  3. The equivalence of the definitions of limit groups.
  4. Limit groups are CAT(0).
  5. Basic theorems: Merzlyakov's theorem and generalizations. Exceptional extensions and Sela's uniform bound theorem.
His assistants will be Lars Louder (a graduate student at University of Utah) and Henry Wilton (a graduate student at Imperial College of London).
