Computing Modular Data of Pointed Fusion Categories
Angus Gruen, Department of Mathematics, Caltech,
A well known invariant of a modular category is the modular data (S,T) which give a projective unitary representation of the modular group. Knowing this invariant vastly aids the understanding of the corresponding category but in general only a small number of these have been explicitly computed. Specializing to the family of modular categories which arise as Drinfel'd centers of pointed fusion categories, I'll discuss how this invariant can be efficiently computed using Galois symmetries and central extensions.
