Zappa-Szép actions of groups on product systems
Boyu Li, Dilian Yang
Let be a group and be a product system over a semigroup . Suppose has a left action on and has a right action on , so that one can form a Zappa-Szép produ…
Zappa-Szép product of a Fell bundle and a groupoid
Anna Duwenig, Boyu Li
We define the Zappa-Szép product of a Fell bundle by a groupoid, which turns out to be a Fell bundle over the Zappa-Szép product of the underlying groupoids. Under certain assumpti…
-Envelope and Dilation Theory of Semigroup Dynamical Systems
Boyu Li
In this paper, we construct, for a certain class of semigroup dynamical systems, two operator algebras that are universal with respect to their corresponding covariance conditions:…
Amenability and functoriality of right-LCM semigroup C*-algebras
Marcelo Laca, Boyu Li
We prove a functoriality result for the full C*-algebras of right-LCM monoids with respect to monoid inclusions that are closed under factorization and preserve orthogonality, and…
