# Seminars and Lectures

We have a range of seminars within the center. Some of them are weekly while others stretch out over a block.

## Reading Seminars and Weekly Seminars

The currently running seminars are listed below. See the calendar for individual talks.

- Algebra/topology seminar: Mondays at 15:15, usually in Auditorium 8.
- Operator algebra seminar: Wednesdays at 15:15, usually in Auditorium 8.
- ALG/NCG/TOP PhD students' seminar: Every other Friday at 15:15, usually in Auditorium 8.
- What is...? seminar: Every other Friday at 15:15, usually in Auditorium 8. A seminar aimed at PhD students and postdocs, inspired by a column in the Notices of the American Mathematical Society. The aim is to give people a taste of mathematics a bit beyond what they know.
