    Abstract We study C*-algebras generated by left regular representations of right LCM one-relator monoids and Artin–Tits monoids of finite type. We obtain structural results concerning nuclearity, ideal structure and pure ...
  • Bryder, Rasmus Sylvester; Ivanov, Nikolay A.; Omland, Tron (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    We study non-ascending HNN extensions acting on their Bass– Serre tree and characterize C*-simplicity and the unique trace property by means of the kernel and quasi-kernels of the HNN extension in question. We also present ...

    On reduced twisted group C*-algebras that are simple and/or have a unique trace
  • Barlak, Selçuk; Omland, Tron; Stammeier, Nicolai (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    We investigate the K -theory of unital UCT Kirchberg algebras QS arising from families S of relatively prime numbers. It is shown that K∗(QS) is the direct sum of a free abelian group and a torsion group, each of which is ...
  • Kaliszewski, S.; Omland, Tron; Quigg, John (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    This is a follow-up to a paper with the same title and by the same authors. In that paper, all groups were assumed to be abelian, and we are now aiming to generalize the results to nonabelian groups. The motivating point ...
