Exactness and LLP Results via Operator System Methods
Kenneth R. Davidson, Vern I. Paulsen, Mizanur Rahaman
In this paper, we employ operator system techniques to investigate structural properties of C*-algebras. In particular, we provide more direct proofs of results concerning exactnes…

Large Perturbations of Nest Algebras
Kenneth R. Davidson
Let and be nests on separable Hilbert space. If the two nest algebras are distance less than 1 ($d(\mathcal{T}(\mathcal{M}),\mathcal{T}(\mathcal{N})) <…

Completely Bounded Norms of -positive Maps
Guillaume Aubrun, Kenneth R. Davidson, Alexander Müller-Hermes +2
Given an operator system , we define the parameters (resp. ) defined as the maximal value of the completely bounded norm of a unit…
