David Penneys: Bicommutant categories from multifusion categories
David Penneys: Bicommutant categories from (multi)fusion categories Abstract: I'll discuss an ongoing joint project with Andre Henriques. Just as a tensor category is a categorification of a ring, and its Drinfeld center is a categorification of the center of a ring, a bicommutant categor

Maxim Kazarian - 3/3 Mathematical Physics of Hurwitz numbers
Hurwitz numbers enumerate ramified coverings of a sphere. Equivalently, they can be expressed in terms of combinatorics of the symmetric group; they enumerate factorizations of permutations as products of transpositions. It turns out that these numbers obey a huge num

Arthur Troupel - Free Wreath Products as Fundamental Graph C*-algebras
The free wreath product of a compact quantum group by the quantum permutation group S+N has been introduced by Bichon in order to give a quantum counterpart of the classical wreath product. The representation theory of such groups is well-known, but some results about their operator algebr
