Welcome to the homepage of the Groups Analysis Geometry Seminar at UTS.
We meet approximately every 2 weeks on campus.
Talks are followed by coffee and discussion at Cornerstone Cafe or Mrs&George depending on which building the talk is in.
The seminar is organised Professor Tony Dooley, Stanley Luk and David Lee, and webpage maintained by Murray Elder.
