Regular Seminar Nikolay Gromov (King's College London)
We discuss the applicability of the Quantum Spectral Curve approach (the most advanced and precise method initially developed for the spectrum of anomalous dimensions of planar N=4 SYM) to the problem of computing structure constants. We give a pedagogical introduction to the QSC formalism for the anomalous dimensions and then present our new results about a more general class observables.

I will discuss the programme to understand conformal field theory via subfactors and twisted equivariant K-theory. This has also resulted in a better understanding of the double of the Haagerup subfactor, which was previously thought to be exotic and un-related to known models.
