Metrics on completely positive maps via noncommutative geometry
Are Austad, Erik Bédos, Jonas Eidesen +2
We study methods of inducing metrics on unital completely positive maps by employing seminorms arising in noncommutative geometry. Our main approach relies on the development of an…
Coactions on C*-algebras and universal properties
Erik Bédos, S. Kaliszewski, John Quigg +1
It is well-known that the maximalization of a coaction of a locally compact group on a C*-algebra enjoys a universal property. We show how this important property can be deduced fr…
Heat properties for groups
Erik Bédos, Roberto Conti
We revisit Fourier's approach to solve the heat equation on the circle in the context of (twisted) reduced group C*-algebras, convergence of Fourier series and semigroups associate…
C*-irreducibility for reduced twisted group C*-algebras
Erik Bédos, Tron Omland
We study C*-irreducibility of inclusions of reduced twisted group C*-algebras and of reduced group C*-algebras. We characterize C*-irreducibility in the case of an inclusion arisin…
Smooth lattice orbits of nilpotent groups and strict comparison of projections
Erik Bédos, Ulrik Enstad, Jordy Timo van Velthoven
This paper provides sufficient density conditions for the existence of smooth vectors generating a frame or Riesz sequence in the lattice orbit of a square-integrable projective re…
Skew products of finitely aligned left cancellative small categories and Cuntz-Krieger algebras
Erik Bédos, S. Kaliszewski, John Quigg
Given a group cocycle on a finitely aligned left cancellative small category (LCSC) we investigate the associated skew product category and its Cuntz-Krieger algebra, which we desc…
