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 ( $K$ -) bounded element of a $W^{*}$ -probability space $(M, φ)$ and, borrowing ideas of Kadison, give an intrinsic characterization of the $^{*}$ -su…
