This Thursday at 12:00, U. Haifa Topology & Geometry seminar on April 4, 2019

Please note the time change. From now on, our seminars start at 12:00.

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

Time   12:00

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.
