Speaker: Vasily Dolgushev, Temple University

Abstract: Inspired by Grothendieck's lego-game, Vladimir Drinfeld introduced, in 1990, a pro-unipotent algebraic group which he called the Grothendieck-Teichmueller group GRT. This group has interesting links to the absolute Galois group of rationals, moduli of algebraic curves, solutions of Kashiwara-Vergne problem, and theory of motives. In my talk, I will show that the group GRT plays a universal role in the study of quantization procedures. My talk is based on results of Thomas Willwacher and myself.
