Multipliers and dual operator algebras
, 2000
"... Abstract. In a previous paper we showed how the main theorems characterizing operator algebras and operator modules, fit neatly into the framework of the ‘noncommutative Shilov boundary’, and more particularly via the left multiplier operator algebra of an operator space. As well as giving new chara ..."

an earlier characterization due to Le Merdy. We also show that the multiplier operator algebras of dual operator spaces are dual operator algebras. Using this we refine several known results characterizing dual operator modules.
Nuclearity for dual operator spaces
, 2010
"... In this short paper, we study the nuclearity for the dual operator space V ∗ of an operator space V. We show that V ∗ is nuclear if and only if V ∗∗ ∗ is injective, where V ∗∗ ∗ is the third dual of V. This is in striking contrast to the situation for general operator spaces. This result is used to ..."

STABLE ISOMORPHISM OF DUAL OPERATOR SPACES
, 2008
"... We prove that two dual operator spaces X and Y are stably isomorphic if and only if there exist completely isometric normal representations φ and ψ of X and Y, respectively, and ternary rings of operators M1, M2 such that φ(X) = [M ∗ 2 ψ(Y)M1] −w∗ and ψ(Y) = [M2φ(X)M ∗ 1]. We prove that this is e ..."

DUAL OPERATOR SYSTEMS
, 807
"... Abstract. We characterize weak * closed unital vector spaces of operators on a Hilbert space H. More precisely, we first show that an operator system, which is the dual of an operator space, can be represented completely isometrically and weak * homeomorphically as a weak * closed operator subsystem ..."

STABLY ISOMORPHIC DUAL OPERATOR ALGEBRAS
"... Abstract. We prove that two unital dual operator algebras A, B are stably isomorphic if and only if they are ∆equivalent [7], if and only if they have completely isometric normal representations α, β on Hilbert spaces H, K respectively and there exists a ternary ring of operators M ⊂ B(H, K) such t ..."

Dualtask interference in simple tasks: Data and theory
 Psychological Bulletin
, 1994
"... People often have trouble performing 2 relatively simple tasks concurrently. The causes of this interference and its implications for the nature of attentional limitations have been controversial for 40 years, but recent experimental findings are beginning to provide some answers. Studies of the psy ..."

Primitives for the manipulation of general subdivisions and the computations of Voronoi diagrams
 ACM Tmns. Graph
, 1985
"... The following problem is discussed: Given n points in the plane (the sites) and an arbitrary query point 4, find the site that is closest to q. This problem can be solved by constructing the Voronoi diagram of the given sites and then locating the query point in one of its regions. Two algorithms ar ..."

The unity and diversity of executive functions and their contributions to complex “Frontal Lobe” tasks: a latent variable analysis
 COGNIT PSYCHOL

A MORITA THEOREM FOR DUAL OPERATOR ALGEBRAS
