The ideal intersection property for essential groupoid C*-algebras
Matthew Kennedy, Se-Jin Kim, Xin Li +2
We characterise, in several complementary ways, étale groupoids with locally compact Hausdorff space of units whose essential groupoid C*-algebra has the ideal intersection propert…
Nonunital operator systems and noncommutative convexity
Matthew Kennedy, Se-Jin Kim, Nicholas Manor
We establish the dual equivalence of the category of (potentially nonunital) operator systems and the category of pointed compact nc (noncommutative) convex sets, extending a resul…
Hyperrigidity of C*-correspondences
Se-Jin Kim
We show that hyperrigidity for a C*-correspondence is equivalent to non-degeneracy of the left action of the Katsura ideal on . Due to the work of Katsou…
Crossed products of operator systems
Samuel J. Harris, Se-Jin Kim
In this paper we introduce the crossed product construction for a discrete group action on an operator system. In analogy to the work of E. Katsoulis and C. Ramsey, we describe thr…
Chromatic numbers and a Lovász type inequality for non-commutative graphs
Se-Jin Kim, Arthur Mehta
Non-commutative graph theory is an operator space generalization of graph theory. Well known graph parameters such as the independence number and Lovász theta function were first g…
A synchronous game for binary constraint systems
Se-Jin Kim, Vern I. Paulsen, Christopher Schafhauser
Recently, W. Slofstra proved that the set of quantum correlations is not closed. We prove that the set of synchronous quantum correlations is not closed, which implies his result,…
