Reflection positivity and Hankel operators -- the multiplicity free case
Maria Stella Adamo, Karl-Hermann Neeb, Jonas Schober
We analyze reflection positive representations in terms of positive Hankel operators. This is motivated by the fact that positive Hankel operators are described in terms of their C…

Chern numbers as half-signature of the spectral localizer
Edgar Lozano Viesca, Jonas Schober, Hermann Schulz-Baldes
Two recent papers proved that complex index pairings can be calculated as the half-signature of a finite dimensional matrix, called the spectral localizer. This paper contains a ne…
