DESCRIPTION:Speakers: Malte Leimbach (MPIM Bonn)\n\nThe spectral truncatio
 n formalism arises from an approach tononcommutative geometry which incorp
 orates constraints on theavailability of spectral data. It was asked by Co
 nnes--van Suijlekomwhether these truncations approximate spectral triples 
 and they proposedto consider this question in the sense of Gromov--Hausdor
 ff distance ofstate spaces. In this talk\, we will refine this question us
 ing Rieffel'scompact quantum metric spaces and Kerr--Li's operator Gromov-
 -Hausdorffdistance. We will discuss convergence of spectral truncations fo
 r toriand for compact quantum groups. This is based on joint work with Wal
 tervan Suijlekom.\n\nhttps://math-events.uni-bonn.de/event/986/
