Abstract:

The q,t-Catalan numbers encode information about the space of diagonal harmonics, but are also quite interesting from a purely combinatorial perspective. They can be computed using properties of certain hyperplane arrangements, some of which have their own connections to other objects of interest. This will be a mostly expository talk exploring the relationship between all of these objects.
