Complexity Meetings take place online and consist of informal talks dedicated to topics of interest in computational complexity theory and related areas. Our goal is for these meetings to serve as a forum for discussion and quick dissemination of results. Meetings will not be recorded and anyone interested in complexity theory is welcome to join.


You can join the mailing list for talk announcements and keep track of them using this calendar
Please contact Igor Oliveira if you have any questions.

A list of talks from 2020-2021 can be found here. You can also access the complete list of meetings through this website.


A Zoom link will be posted here shortly before each meeting.
