Crystal limits of compact semisimple quantum groups as higher-rank graph algebras
Matassa, Marco; Yuncken, Robert (Journal für die Reine und Angewandte Mathematik;, Peer reviewed; Journal article, 2023)Let Oq [K] denote the quantized coordinate ring over the field C(q) of rational functions corresponding to a compact semisimple Lie group K, equipped with its ∗-structure. Let A0 ⊂ C(q) denote the subring of regular functions ... -
Regularity of twisted spectral triples and pseudodifferential calculi
Matassa, Marco; Yuncken, Robert (Journal of Noncommutative Geometry;, Journal article; Peer reviewed, 2019-03-13)We investigate the regularity condition for twisted spectral triples. This condition is equivalent to the existence of an appropriate pseudodifferential calculus compatible with the spectral triple. A natural approach to ...
