SUMMARY:The Zappa–Szép product of groupoid twists - Anna  Duwenig (Univ

DESCRIPTION:The Zappa&ndash\;Sz&eacute\;p (ZS) product of two groupoids is
  a generalization of the semi-direct product: instead of encoding one grou
 poid action by homomorphisms\, the ZS product groupoid encodes two (non-ho
 momorphic\, but &ldquo\;compatible&rdquo\;) actions of the groupoids on ea
 ch other. Together with my collaborator Boyu Li\, I have been working on v
 arious ways of generalizing this construction to the world of C*-algebras.
  In this talk\, I will introduce you to our generalization of the ZS produ
 ct to two twists over groupoids and\, if time permits\, I will show how ou
 r construction ties in with Weyl twists from Cartan pairs arising from Kum
 jian--Renault theory.&nbsp\;\nBased on joint work with Boyu Li\, New Mexic
 o State University.
