Combinatorics, Algebra and Geometry Seminar (CAGS)
The Seminar this Fall semester of 2009 meets 11:30 AM -- 12:20 PM on Fridays in Science & Technology Building I Room 242 CAGS Chair: Walter Morris The CAGS is intended as an informal venue, where faculty members, graduate students, visitors from near and far can come and give informal talks on their research, interesting new topics, open problems or just share their thoughts/ideas on anything interesting relating to combinatorics, algebra and discrete geometry. Needless to say, all are welcome to attend, and those who want to give a talk, should email me (Walter) the title and a short abstract. For other talks/presentations, check our departmental Colloquium, or our departmental Applied and Computational Math Seminar or our departmental Topology seminar. Fall 2009 September 18~ Survey of
