The Baltimore Number Theory Seminar has existed since the fall of 2015. The current core group consists of Vefa Goksel, Angel Kumchev, and Nathan McNew; other colleagues have also expressed interest in joining us in the future. For the time being, we are planning to meet at 4:30 pm on Tuesdays in YRÂ 320. If you are interested in giving a talk or joining us as a permanent member, feel free to contact Angel or Nathan.
