Hi topologists,

Jing Tao asked me to pass this along to our group.

Best,

Hi Neil and Mehmet,

I hope you are doing well. I am emailing because I would like to invite you and your colleagues/students to participate in a new event I'm organizing at OU. The event is called "Hyperbolic Saturdays". Basically, I will have visitors come and lead a half-day discussion (usually on a Saturday) about a topic of their expertise. The topics are chosen in advance but the visitors are not supposed to prepare a seminar talk. I'm really hoping for a fruitful, lively exchange between the visitors and the participants.

This event is funded by my NSF career grant. I can reimburse participants outside of OU for their travel (at full rate) and give a small per diem.

Here's a website for the upcoming speakers: http://www.math.ou.edu/~jing/hyperbolic/

The first hyperbolic Saturday will take place on August 24. The visitor is Kasra Rafi and the topic will be on basic hyperbolic geometry, particularly the action of SL(2,Z) on SL(2,R). The location will be somewhere in the math department but the room is TBD.

I anticipate the schedule of the event to look as follows:

9:30-10 -- coffee

10-12-ish -- discussion (with break)

lunch

If you could pass the word to people in your department who might be interested, that would be great. Please tell them to contact me if they are interested.

Thank you in advance. Have a great semester!

Best,

JIng
