Untwisting twisted spectral triples
Magnus Goffeng, Bram Mesland, Adam Rennie
We examine the index data associated to twisted spectral triples and higher order spectral triples. In particular, we show that a Lipschitz regular twisted spectral triple can alwa…
Estimating Dixmier traces of Hankel operators in Lorentz ideals
Magnus Goffeng, Alexandr Usachev
In this paper we study Dixmier traces of powers of Hankel operators in Lorentz ideals. We extend results of Engliš-Zhang to the case of powers and general Lorentz ideals…
Smale space C*-algebras have nonzero projections
Robin J. Deeley, Magnus Goffeng, Allan Yashinski
The main result of the present paper is that the stable and unstable C*-algebras associated to a mixing Smale space always contain nonzero projections. This gives a positive answer…
Constructing KMS states from infinite-dimensional spectral triples
Magnus Goffeng, Adam Rennie, Alexandr Usachev
We construct KMS-states from -summable semifinite spectral triples and show that in several important examples the construction coincides with well-known direct cons…
