General information
20+ years of categorification
The year 2016 is (roughly) the 22th year after Crane and Frenkel
introduced the notion of “categorification” in their attempt
to extend the Witten-Reshetikhin-Turaev $2+1$-dimensional TQFT construction to the
four-dimensional world.
Since then categorification has grown into a field on its own with several
different aspects to it; some more combinatorial in nature, some algebraical
or topological.
To understand all different aspects of it is a far-fetch goal, but
to understand categorification at least partially from different
viewpoints (and their possible/existing applications)
is the main purpose of this workshop and we hope that this will turn out to be
useful and interesting for all the participants.
Aim and scope of the workshop
The aim of this workshop is to bring together researchers interested in
“categorical representation theory” and their applications, as well as
students or researchers from related fields who want to learn about
the “Why and how?” of categorification.
Structure of the lectures
The workshop consists of two parts. In the first three days there will
be twelve lectures in total by the four main speakers. All of them will give introductory talks
on different aspects of categorification, covering (in some details) topics as:
- Lie theoretic aspects of categorification (as for instance categorification via category $\mathcal{O}$)
- Categorification from the viewpoint of physics (“categorification of
Chern-Simons theory” and related questions)
- Categorification of link polynomials (with Khovanov homology as a main player)
- Categorification of quantum groups (KL-R algebras and 2-categories etc.)
Then (in the last two days) there will be eight additional lectures by the other speakers on
different aspects of the modern developments within the field.
Each talk (main lectures and the additional talks) is a 60 minutes talk (plus time for questions),
and will be held in the Lipschitz-Saal in the Mathematical Institute of the University of Bonn.
