Abstract:

Exact Structures can be placed on the additive category of operator  modules over an operator algebra. We do this on order to discuss global dimension for operator algebras. In this talk we provide an overview with a focus on global dimension 0. Properties of the Haagerup tensor product play a decisive role. This is joint work with Martin Mathieu.
