Associativity of crossed products by partial actions, enveloping actions and partial representations
M. Dokuchaev, R. Exel
Given a partial action αof a group G on an associative algebra A we consider the crossed product A x_αG. Using the algebras of multipliers of ideals of A we prove that A x_αG is as…
On embeddings of full amalgamated free product C*-algebras
Scott Armstrong, Ken Dykema, Ruy Exel +1
We examine the question of when the *-homomorphism of full amalgamated free product C*-algebras λ: A *_D B --> A' *_{D'} B', arising from compatible inclusions of C*-algebras A in…
C*-Algebras, Approximately Proper Equivalence Relations, and Thermodynamic Formalism
R. Exel, A. Lopes
We introduce a non-commutative generalization of the notion of (approximately proper) equivalence relation and propose the construction of a "quotient space". We then consider cert…
C*-Algebras of Irreversible Dynamical Systems
R. Exel, A. Vershik
We show that certain C*-algebras which have been studied among others by Arzumanian, Vershik, Deaconu, and Renault in connection to a measure preserving transformation of a measure…
