Abstract:
The soft tori constitute a continuous deformation, in a very precise sense, from the commutative -algebra to the highly non-commutative -algebra . Since both of these -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.
