Hyperbolic Lunch

Hyperbolic lunch is an informal talk that takes place at noon in my office (BA 6188). They generally last around 90 minutes and the talks are often interrupted by many questions. People bring their lunches to my office and eat as they listen to the talk. The audience consists of graduate students and postdocs and an occasional faculty or an undergraduate interested in hyperbolic geometry or related topics in geometry, topology, group theory and dynamics. The topics are often what someone has learned recently and not necessarily a result by the speaker.


If you are in Toronto and have a fun topic you can talk about, you should consider doing one of these lunches. The talks should be accessible to graduate students. We appreciate beautiful math even when it is elementary and would like to know about math as much as about stories of how math gets done.
