Planar algebras that count graph colorings
An integral anyon model is one where all of the quantum dimensions are integers. Simply put, you have linear combinations of graphs in the plane, subject to local relations, so that every closed graph evaluates to an integer. I believe every integer should be counting something. I will describe some cases where, with some adjustment, this integer is counting some kind of graph colorings.
