Quasi-multipliers and algebrizations of an operator space. II. Extreme points and quasi-identities
(2016)Let X be an operator space, let φ be a product on X, and let denote the algebra that one obtains. We give necessary and sufficient conditions on the bilinear mapping φ for the algebra to have a completely isometric ... -
The unit ball of an injective operator space has an extreme point
(Journal of Mathematical Analysis and Applications, July 2018)We define an -TRO as an off-diagonal corner of an-algebra, and show that the unit ball of an -TRO has an extreme point. In particular, the unit ball of an injective operator space has an extreme point, which answers a ...
