ISU Algebra Seminar

The ISU Algebra Seminar will meet for the Fall 2018 semester on Wednesdays from 10:00 a.m. to 10:50 a.m. in STV 310. (Note, some weeks the seminar will be on Thursdays from 1:00 - 1:50. Please look for announcements for these alternate times.) Please let us know if you would like to give a talk. Everyone is welcome to attend. We make an effort to make the talks accessible for the mathematician on the street. Some of the talks will also be accessible to graduate students.

Announcements of upcoming seminars are sent by e-mail to all members of the ISU math department. If you are not a member of the ISU Math department and if you would like to receive seminar announcements, please send e-mail to gzyamsku@ilstu.edu (with the z removed).
