Generalized free wreath products and their operator algebras
Pierre Fima, Arthur Troupel
We develop a new approach on free wreath products, generalizing the constructions of Bichon and of Fima-Pittau. We show stability properties for certain approximation properties su…

Operator algebras of free wreath products
Pierre Fima, Arthur Troupel
We give a description of operator algebras of free wreath products in terms of fundamental algebras of graphs of operator algebras as well as an explicit formula for the Haar state…
