# Open Problem Session – Dec 14

The organizers of the Graphs and Matroids Seminar would like to invite you to participate in our Open Problem Session!

The session will take place on Tuesday, December 14 from 1:30 to 4:00pm EST with social time afterwards on Gather Town. For each problem, we’ll have ~5 minutes for the presentation followed by ~5 minutes for discussion. We’re planning to have two sessions of about an hour each with a break in between.

Call for presenters: If you would like to present an open problem, please email Shayla (shaylaredlin at gmail dot com) and let us know if you would prefer presenting in the first hour or the last hour of the session.

More details about the schedule and how to attend will be posted closer to Dec 14.

– Jim, Peter, and Shayla
