Abstract:

The soft tori constitute a continuous deformation, in a very precise sense, from the commutative $C^*$-algebra $C(\mathbb{T} ^2)$ to the highly non-commutative $C^*$-algebra $C^*(\mathbb{F} _2)$. Since both of these $C^*$-algebras are known to have a separating family of finite dimensional representations, it is natural to ask whether that is also the case for the soft tori. We show that this is in fact the case.
