Braided join comodule algebras of Galois objects
Ludwik Dabrowski, Tom Hadfield, Piotr M. Hajac +1
We construct the join of noncommutative Galois objects (quantum torsors) over a Hopf algebra H. To ensure that the join algebra enjoys the natural (diagonal) coaction of H, we brai…

Equivariant Join and Fusion of Noncommutative Algebras
Ludwik Dabrowski, Tom Hadfield, Piotr M. Hajac
We translate the concept of the join of topological spaces to the language of -algebras, replace the -algebra of functions on the interval with evaluation maps at…
