Dg enhancements of triangulated categories and their uniqueness

Abstract: It is well known that often some intrinsic defects of triangulated categories can be avoided by enhancing them to suitable higher categorical structures, like (pretriangulated) dg categories. However, despite significant progress made in recent years, the relation between the triangulated and the dg level is not yet completely clear, and some foundational questions have received only partial answers so far. After presenting the general picture, I will report on a joint work (partly in progress) with Neeman and Stellari about uniqueness of dg enhancements.

Longitudinal Algebra and Geometry Open ONline Seminar (LAGOON)

Series comments: Description: Research webinar series

The LAGOON webinar series was supported as part of the International Centre for Mathematical Sciences (ICMS) and the Isaac Newton Institute for Mathematical Sciences (INI) Online Mathematical Sciences Seminars and is now sponsored by the University of Cologne and the University of Pavia. Please register here to obtain the Zoom link and password for the meetings.

LAGOON will take place online every last Wednesday of the month from 14:00-15:00 (Time Zone Berlin, Rome, Paris).

Videos of the talks can be viewed here.

Video recordings of past talks until April 2022 can still be viewed on the ICMS webpage here.
