Coactions of compact groups on
S. Kaliszewski, Magnus B. Landstad, John Quigg
We prove that every coaction of a compact group on a finite-dimensional -algebra is associated with a Fell bundle. Every coaction of a compact group on a matrix algebra is imp…
Polynomial functions for locally compact group actions
Magnus B. Landstad, Alfons Van Daele
Consider a locally compact group and a locally compact space . A local right action of on is a continuous map from an open subset of the…
Finite quantum hypergroups
Magnus B. Landstad, Alfons Van Daele
A finite quantum hypergroup is a finite-dimensional unital algebra over the field of complex numbers. There is a coproduct on , a coassociative map from to …
R-coactions on -algebras
S. Kaliszewski, Magnus B. Landstad, John Quigg
We give the beginnings of the development of a theory of what we call "R-coactions" of a locally compact group on a -algebra. These are the coactions taking values in the maxi…
Tensor coaction functors
S. Kaliszewski, Magnus B. Landstad, John Quigg
We develop an approach, using what we call "tensor coaction functors", to the "-crossed-product" functors of Baum, Guentner, and Willett. We prove that the tensor functo…
Ola Bratteli and his diagrams
Tone Bratteli, Trond Digernes, George Elliott +6
This article discusses the life and work of Professor Ola Bratteli (1946--2015). Family, fellow students, his advisor, colleagues and coworkers review aspects of his life and his o…
