MOTIVIC HOMOTOPY THEORY and APPLICATIONS 3.30 pm, Lecture Hall 6 Lecture 3:Affine homotopy invariance of G-torsors Anand Sawant TIFR. 08-11-19 Abstract Since its inception in the foundational work of Morel and Voevodsky in the 1990's, motivic (or A^1)-homotopy theory has provided a systematic framework to successfully adapt several techniques of algebraic topology to the realm of algebraic geometry by having the affine line A^1 play the role of the unit interval. In the last 20 years, motivic homotopy theory has led to spectacular applications such as Voevodsky’s proof of the Milnor and Bloch-Kato conjectures. In this mini-course, I will introduce motivic homotopy theory and discuss some of its applications with emphasis on algebraic groups.
