Garside's Solution to the Conjugacy Problem in the Braid Group

Tristram de Piro
(Camerino)
Abstract
  I will discuss Garside's representation of elements of the braid group in terms of "half- twists" and the corresponding solution to the Conjugacy Problem, originally posed by Artin. If time permits, I will discuss some geometric implications of this result.

Blurred exponentiation and the geometry of exponential fields

Jonathan Kirby
(UIC, Chicago)
Abstract
  I will discuss the proof that the exponential algebraic closure operator on the complex exponential field is isomorphic to the pregeometry which controls the "pseudoexponential" field.
