Topology Reading Group Spring 2020
Time: 2PM to 3PM on Thursdays
Location: Currently this seminar is being conducted remotely, please email me at gage (dot) martin (at) bc (dot) edu if would like to participate in the seminar
Our goal for this informal seminar is to have a place to share what you're learning about with other topology graduate students. Interested in speaking? Email me!
