Classifying fusion categories

March 12 to March 16, 2012

at the

American Institute of Mathematics, Palo Alto, California

organized by

Scott Morrison, Eric Rowell, and Noah Snyder

Original Announcement

This workshop will be devoted to the classification problem for fusion categories, including those with additional structure, e.g. ribbon and modular fusion categories. More specifically, we will focus on the development and application of both theoretical and computational techniques for classifying fusion categories that are "small" in various senses.

This workshop will bring together interested mathematicians working in Topology, Representation Theory and Subfactor Theory with two main goals:

  1. share techniques and encourage collaborative approaches among these research groups, and
  2. develop hybrid techniques to classification with a view towards establishing a long-term classification program.
Among the interpretations of "small" that will be considered are: small rank, low-dimensional simple objects, bounded global Frobenius-Perron dimension and global Frobenius-Perron dimension having few prime divisors.

Two secondary goals are:

  1. to compile an up-to-date catalog of known classifications and
  2. to search for exotic fusion categories i.e. not related to quantum groups or quasi-Hopf algebras.
