On closed Lie ideals of certain tensor products of C*-algebras II

Abstract

We identify all closed Lie ideals of $A \otimes^{\alpha} B$ and $B(H) \otimes^{\alpha} B(H)$, where $\otimes^{\alpha}$ is either the Haagerup tensor product, the Banach space projective tensor product or the operator space projective tensor product, $A$ is any simple C*-algebra, $B$ is any C*-algebra with one of them admitting no tracial states, and $H$ is an infinite dimensional separable Hilbert space. Further, generalizing a result of Marcoux, we also identify all closed Lie ideals of $A\otimes^{\min} B$, where $A$ is a simple C*-algebra with at most one tracial state and $B$ is any commutative C*-algebra.
