Topology and Geometry Seminar

The seminar aims to introduce research topics in topology, geometry and its interactions with other sciences on a simple level. Some topics are discussed over a 3-week period led by the same speaker (as a mini-course). Anyone interested in mathematics is welcome to attend.

Summer 2018

The seminar will meet at 3:00 pm on Wednesday at Lab 3, B700 unless otherwise noted.
