Schur tensor product of operator spaces

Vandana Rajpal, Ajay Kumar, Takashi Itoh

We develop a systematic study of the schur tensor product both in the category of operator spaces and in that of $C^{*}$ -algebras.

Numerical Radius Norms on Operator Spaces

Takashi Itoh, Masaru Nagisa

We introduce a numerical radius operator space $(X, W_{n})$ . The conditions to be a numerical radius operator space are weaker than the Ruan's axiom for an operator space $…

The numerical radius Haagerup norm and Hilbert space square factorizations

Takashi Itoh, Masaru Nagisa

We study a factorization of bounded linear maps from an operator space $A$ to its dual space $A^{*}$ . It is shown that $T : A ⟶ A^{*}$ factors through a pair of a column…
