The Operator Systems of Hankel Matrices and Complex Polynomials

Thomas Sinclair, Shengwei Qiu

We investigate the operator system structure of finite Hankel matrices and its connection with complex polynomials on the real line. Using polynomial matrix spectral factorization,…

Approximate factorization properties for operator systems

Roy Araiza, Larissa Kroell, Travis Russell +1

We show that many of the standard nuclearity properties considered in the literature for the hierarchy of operator system tensor products can be expressed as approximate factorizat…

On definability of C*-tensor norms

Isaac Goldbring, Thomas Sinclair

We initiate the study of definability (in the model-theoretic sense) of C*-tensor norms. We show that neither the minimal nor maximal tensor norms are definable uniformly over all…

A short proof of the existence of the injective envelope of an operator space

Thomas Sinclair

We use Ellis' lemma to give a simple proof of the existence of the injective envelope of an operator space first shown by work of Hamana and Ruan.

Totally Bounded Elements in W*-probability Spaces

Hiroshi Ando, Jananan Arulseelan, Isaac Goldbring +2

We introduce the notion of a totally (-) bounded element of a -probability space and, borrowing ideas of Kadison, give an intrinsic characterization of the -su…

Model Theory of Operator Systems and C-Algebras

Thomas Sinclair

We survey the model theory of operator systems and C-algebras.
