Quotients of Banach algebras acting on -spaces
Eusebio Gardella, Hannes Thiel
We show that the class of Banach algebras that can be isometrically represented on an -space, for , is not closed under quotients. This answers a question asked by Le…
Tensor products and regularity properties of Cuntz semigroups
Ramon Antoine, Francesc Perera, Hannes Thiel
The Cuntz semigroup of a C*-algebra is an important invariant in the structure and classification theory of C*-algebras. It captures more information than K-theory but is often mor…
Functoriality of group algebras acting on -spaces
Eusebio Gardella, Hannes Thiel
We continue our study of group algebras acting on -spaces, particularly of algebras of -pseudofunctions of locally compact groups. We focus on the functoriality properties…
Group algebras acting on -spaces
Eusebio Gardella, Hannes Thiel
For we study representations of a locally compact group on -spaces and -spaces. The universal completions and of $…
Banach algebras generated by an invertible isometry of an -space
Eusebio Gardella, Hannes Thiel
We provide a complete description of those Banach algebras that are generated by an invertible isometry of an -space together with its inverse. Examples include the algebra $P…
Semiprojectivity with and without a group action
N. Christopher Phillips, Adam P. W. Sørensen, Hannes Thiel
The equivariant version of semiprojectivity was recently introduced by the first author. We study properties of this notion, in particular its relation to ordinary semiprojectivity…
