Seminar this afternoon
by Jesse Johnson 29 Nov '12

29 Nov '12

This is a reminder that Weiping Li will give the topology seminar this afternoon at 3:30 in MSCS 514. Title: An $SL_2(\mathbb{C})$ topological invariant of knots Abstract: We show that the $SL_2(\mathbb{C})$ algebro-geometric invariant defined by W.Li and Qingxue Wang for knots is indeed an $SL_2(\mathbb{C})$ topological invariant. The main ingredient is our short geometric proof of the coincidence of the algebro-geometric multiplicity and topological multiplicity of the intersection of curves on a smooth surface. The talk will review some backgrounds on invariants related issues from $SU(2)$ to $SL_2(\mathbb{C})$.

Spring reading group?
by Jesse Johnson 24 Nov '12

24 Nov '12

Dear Topologists and Friends of Topology, A few of us have talked about starting a reading group in the spring - We'll choose a topic and one or more papers or notes on the topic, then we'll all read these papers and take turns giving weekly presentations to the rest of the group. Ideally, the topic should be something that no one in the group knows much about. If you are interested in being involved, please let me know, and also send a list of any suggested topics. Jesse
