Why are fusion categories interesting?
The relationship between (sufficiently nice) fusion categories and subfactor planar algebras is a little complicated. There are three things to keep in mind.
Almost trivially, a pivotal fusion catego …

Why are fusion categories interesting?
The analogy with finite groups is not quite as strong as Greg suggests. If you're looking at a braided fusion category then the dimensions of objects all divide the the global dimension (the sum of th …
