Rigidity for Isomorphisms between Operator Algebras with Commutative Diagonals
Elias G. Katsoulis, Feifei Miao, Wenming Wu +1
We show that two families of operator algebras, the CSL algebras of multiplicity free CSLs and the semicrossed products of commutative C-algebras, demonstrate a strong form of…

Cuntz-Nica-Pimsner algebras associated to product systems over quasi-lattice ordered groupoids
Feifei Miao, Liguang Wang, Wei Yuan
We characterize Cuntz-Nica-Pimsner algebras for compactly aligned product systems over quasi-lattice ordered groupoids. We show that the full cross sectional -algebras of Fell…

Co-universal -algebras for product systems over finite aligned subcategories of groupoids
Feifei Miao, Liguang Wang, Wei Yuan
The product systems over left cancellative small categories are introduced and studied in this paper. We also introduce the notion of compactly aligned product systems over finite…
