Integrality Properties of Topological Fundamental Groups
Hélène Esnault
10:00am|Wolfensohn Hall and Remote Access

Abstract: The talk is based on joint work with Michael Groechenig and Johan de Jong.
We single out integrality properties of the topological fundamental group of smooth quasi-projective complex varieties which rely on the Langlands program (both...

Measure Doubling for Small Sets in SO(3,R)
Yifan Jing
2:00pm|Simonyi 101 and Remote Access

Let SO(3,R) be the 3D-rotation group equipped with the real-manifold topology and the normalized Haar measure \mu. Confirming a conjecture by Breuillard and Green, we show that if A is an open subset of SO(3,R) with sufficiently small measure, then...
