MATH Seminar: “Higher Morita Categories”, Rune Haugseng, 13.30PM April 12 (EN)

You are cordially invited to the Topology Seminar organized by the Department of Mathematics.

Speaker: Rune Haugseng (Norwegien University of Science and Technology)

“Higher Morita categories”

Abstract: Classical Morita theory for associative algebras can be described in terms of a 2-category with associative algebras as objects, bimodules as morphisms, and bimodule homomorphisms as 2-morphisms; this can be further enhanced to a double category that also includes algebra homomorphisms. More generally, we can consider 2-categories and double categories of enriched categories and bimodules between them. I will discuss homotopical versions of these structures and their higher-dimensional generalizations to $E_n$-algebras and enriched n-categories, which are of interest as targets for fully extended TQFTs.
