Time: Wed 2023-09-20 11.00 - 12.00
Location: Albano, Cramérrummet

Abstract.
In this talk, we are going discuss some the structural properties of Nevanlinna measures, i.e. Borel measures that arise in the integral representation of Herglotz-Nevanlinna functions. In particular, we are going to present a characterization of these measures in terms of their Fourier transform and characterize measures supported on hyperplanes including extremal measures. The talk is based on a joint publication with Eero Saksman.
