For a prime p, the McKay conjecture suggests a bijection between the set of irreducible characters of a finite group with p’-degree and the corresponding set for the normalizer of a Sylow p- subgroup. Navarro’s refinement suggests that the values of the characters on either side of this bijection should also be related, proposing that the bijection commutes with certain Galois automorphisms. Recently, Navarro–Späth–Vallejo have reduced the McKay–Navarro conjecture to certain “inductive” conditions on finite simple groups. I’ll discuss joint work with Lucas Ruhstorfer, in which we prove that these inductive McKay–Navarro (also called the inductive Galois–McKay) conditions hold when p = 2 for several groups of Lie type.

The inductive McKay—Navarro conditions for the prime 2 and some groups of Lie type.

This talk should cover the Levi-Wen string net construction and the relationship to the Turaev-Viro construction. Depending on the presenter this could be a very physics-leaning talk.

The talks are in-person with a computer pointed at the blackboard zoom option: https://cuboulder.zoom.us/j/98979344859?pwd=K3ZrTWt4Wkk1cllOQ1pkcW4vZ1FCZz09 Meeting ID: 989 7934 4859 Passcode: 787231
