The Haagerup property for arbitrary von Neumann algebras
Martijn Caspers, Adam Skalski
We introduce a natural generalization of the Haagerup property of a finite von Neumann algebra to an arbitrary von Neumann algebra (with a separable predual) equipped with a normal…
The quantum algebra of partial Hadamard matrices
Teo Banica, Adam Skalski
A partial Hadamard matrix is a matrix whose rows are pairwise orthogonal. We associate to each such a certain quantum semigroup of quantum p…
Projective limits of quantum symmetry groups and the doubling construction for Hopf algebras
Adam Skalski, Piotr M. Sołtan
The quantum symmetry group of the inductive limit of C*-algebras equipped with orthogonal filtrations is shown to be the projective limit of the quantum symmetry groups of the C*-a…
The Haagerup property for locally compact quantum groups
Matthew Daws, Pierre Fima, Adam Skalski +1
The Haagerup property for locally compact groups is generalised to the context of locally compact quantum groups, with several equivalent characterisations in terms of the unitary…
