DESCRIPTION:Speaker: Floris Vermeulen (University of Münster)\n\nTitle: K
 ontsevich-Zagier in valued fields\n\nAbstract: A period is a real number
  which is the measure of a semialgebraic set defined over the rationals.
  The ring of periods was formally introduced by Kontsevich and Zagier in
  2001\, and remains a rather mysterious object. Kontsevich and Zagier co
 njectured that every equality between periods can already be deduced fro
 m simple integration rules such as additivity\, change of variables\, an
 d the fundamental theorem of calculus. While this conjecture remains com
 pletely open\, a p-adic analogue was proven by Cluckers-Halupczok. In jo
 int work with Mathias Stout\, we use motivic integration and h-minimalit
 y to prove a general version of the Kontsevich-Zagier conjecture in hens
 elian valued fields.\n\nIn this talk I will introduce periods in the rea
 ls and discuss the p-adic analogue due to Cluckers-Halupczok. Afterwards
  I will introduce motivic integration and discuss the period conjecture 
 in this generality. Time permitting\, I will give some ideas of the proo
 f.
