    Bedos, Erik Christopher; Omland, Tron Ånen (Research report / Forskningsrapport, 2009)
  • Primitivity of some full group C*-algebras 
    Bedos, Erik Christopher; Omland, Tron Ånen (Research report / Forskningsrapport, 2010)
    We show that the full group C*-algebra of the free product of two nontrivial countable amenable discrete groups, where at least one of them has more than two elements, is primitive. We also show that in many cases, this ...
