The Atiyah-Singer index formula for subelliptic operators on contact manifolds
The Annals of Mathematics is often considered the most prestigious journal of mathematics research. Lewis Bowen was a member of our department when he wrote an article in Ann. Math. in 2007-2009 (he is now at Texas A&M), and Erik van Erp just joined our department this Fall 2012. Their articles are:
