As was mentioned here, there is a math conference for undergraduates, graduate students, and faculty in Weatherford, OK on March 27-28, 2009. There will be lots of good talks, a chance to meet math folks from OK and AR, and if you’re an undergrad, then you can participate in the team math competition. Talk to Keri Kornelson or Nikola Petrov if you are interested in attending, or at least interested in hearing more about it!
P.S. The OU Math department will be covering the costs for students who attend the meeting, so don’t let that deter you!
