Large Perturbations of Nest Algebras

Kenneth R. Davidson

Let $M$ and $N$ 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 $k$ -positive Maps

Guillaume Aubrun, Kenneth R. Davidson, Alexander Müller-Hermes +2

Given an operator system $S$ , we define the parameters $r_{k} (S)$ (resp. $d_{k} (S)$ ) defined as the maximal value of the completely bounded norm of a unit…
