The gauge group and perturbation semigroup of an operator system

HIGHLIGHTS

• who: Mathematics Subject Classification et al. from the Institute for, Astrophysics and PArticle Physics, Radboud University Nijmegen, Heyendaalseweg, AJ Nijmegen, Netherlands have published the research work: The Gauge Group and Perturbation Semigroup of an Operator System, in the Journal: (JOURNAL)
• what: The authors show that there is a group homomorphism from G(E) to the set of unital completely positive maps on E. In Section 4.1, the authors show that the gauge group G(Toepn ) of Toeplitz system Toepn is independent of n, and G(Toepn ) ~=U × (U ⋊ Z2 ). The authors show the relationship . . .
