Order Bounded Maps and Operator Spaces
Mar 6, 2015 1pm, 646 PGH
Abstract
In this talk, I will introduce the concept of order bounds and order bounded
maps on ordered vector spaces over the real numbers. I will use these concepts to
characterize self-adjoint subspaces of C*-algebras. As an application, I will
demonstrate necessary and sufficient conditions under which a completely positive
completely contractive map from a self-adjoint operator space to B(H) has a completely
positive completely contractive lift, generalizing the well-known Arveson extension
theorem.
