Geometry, Topology and Dynamics Seminar

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

Fall 2018

The seminar will meet at 4:00 pm on Wednesday at Lab 3, B700 unless otherwise noted.
