Postdoc Seminar

IMA Postdoc Seminars are given weekly throughout the fall and spring semesters. Postdocs present on a variety of mathematical topics that may be unrelated to the current annual program theme. IMA visitors and University of Minnesota faculty are also invited to present on subjects of interest. Titles, abstracts, and speakers for each seminar will be posted as available.

The 2017-18 seminars will take place Fridays from 9:30 to 11 a.m. unless otherwise noted.
