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…
