Rigidity theory for -dynamical systems and the "Pedersen Rigidity Problem"
S. Kaliszewski, Tron Omland, John Quigg
Let be a locally compact abelian group. By modifying a theorem of Pedersen, it follows that actions of on -algebras and are outer conjugate if and only if ther…
Dynamical systems and operator algebras associated to Artin's representation of braid groups
Tron Omland
Artin's representation is an injective homomorphism from the braid group on strands into , the automorphism group of the free group $\math…
On reduced twisted group C*-algebras that are simple and/or have a unique trace
Erik Bédos, Tron Omland
We study the problem of determining when the reduced twisted group C*-algebra associated with a discrete group G is simple and/or has a unique tracial state, and present new suffic…
C*-simplicity of free products with amalgamation and radical classes of groups
Nikolay A. Ivanov, Tron Omland
We give new characterizations to ensure that a free product of groups with amalgamation has a simple reduced group C*-algebra, and provide a concrete example of an amalgam with tri…
