Geometry & Topology Seminar
Speaker: Mattia Ornaghi (Ben Gurion University of Negev)
Topic: Localizations of the category of A-categories and Internal Homs.
Place: room 614 in the Science & Education Building
Date: Thursday, April 4, 2019
In the first part of the talk we prove that the localizations of the categories of dg categories, of cohomologically unital and strictly unital Acategories with respect to the corresponding classes of quasi-equivalences are all equivalent. As an application, in the second part, we give a complete proof of a claim by Kontsevich stating that the category of internal Homs for two dg categories can be described as the category of strictly unital Afunctors between them. This is a joint work with Prof. A. Canonaco and Prof. P. Stellari arXiv:1811.07830.
