Wild orbits and generalised singularity modules: stratifications and quantisation
Damien Calaque, Giovanni Felder, Gabriele Rembado +1
We study truncated gauge-orbits through principal parts of irregular-singular connection germs, in the untwisted/unramified setting: for any connected complex reductive structure g…

Orthogonal Polynomials with Complex Densities and Quantum Minimal Surfaces
Giovanni Felder, Jens Hoppe
We show that the discrete Painlevé-type equations arising from quantum minimal surfaces are equations for recurrence coefficients of orthogonal polynomials for indefinite hermitia…

Hecke modifications of conformal blocks outside the critical level
Raschid Abedin, Giovanni Felder, Robert Windesheim
We define Hecke modifications of conformal blocks over affine Lie algebras at non-critical level by using the Hecke modifications of the underlying -bundles. We show that this p…
