Featured Speaker: Dan Abramovich (Brown University)

Title: Stacks at the service of resolution of singularities.

Abstract: I'll report on joint work with Temkin and Wlodarczyk, with Quek, and with Schober, using stacks to give resolution algorithms. These include Deligne--Mumford stacks (with weighted blowups) and Artin stacks (with multi-weighted blowups). That said, having looked at what's out there, I thought I'll teach you how to blow up.

Zoom info available upon request.

Seminar Covid Statement
A notice to non-MIT seminar participants: at this time, not all seminars are open to the general public, and access to the MIT campus is highly regulated. Please check the seminar webpage or with the event organizer and confirm whether the seminar you'd like to attend is open to non-MIT (i.e. without CovidPass) attendees.
Some seminars may offer a Zoom option for off-campus participants.
To access MIT buildings for a math seminar without MIT's CovidPass, you must be invited via a Tim Ticket ahead of time. There are no exceptions; please make sure to plan accordingly before coming to campus. To be able to activate the Tim Ticket, the attendee will need to submit an attestation about vaccination and health status and provide contact info.
Finally, a reminder to all in-person participants. MIT Covid policies must be adhered to: remember to keep your mask on while inside buildings, eating food is not allowed within lecture rooms, and if you are feeling sick on the day of the talk, please stay home!
