The graduate program in mathematical logic at the University of Illinois at Urbana-Champaign is one of the most active such programs in the world, with a large community of faculty and students. Most aspects of the subject are represented here, especially model theory and its applications and descriptive set theory. A particular emphasis of our program is on the connections of logic to other important areas of mathematics.

## Weekly Logic Seminars

**Logic Seminar**

Tuesdays at 1:00pm

This seminar is preceded by "logic lunch" which starts at 11:30am; meet in the mailroom (250 Altgeld). For announcements of talks click here.**Model Theory and Descriptive Set Theory Seminar**

Fridays at 4:00pm

Often this seminar is devoted to carefully reading an important new paper or covering a currently active research topic. For announcements of talks click here. This seminar is followed by a social gathering at around 5:10pm -- the location is announced by email to the logic list (see below).**Email announcements**

The Illinois logic group maintains a distribution list of people interested in news about activities of our logic program. Anyone interested in being added to this list should send email to Philipp Hieronymi.
