Abstract: 

In Winter & Zacharias (2009), a structure theorem is given for orthogonality-preserving completely positive contractions between C*-algebras. A consequence of this theorem is that there exists a one-to-one correspondence between such maps and *-homomorphisms between the cone of the domain and the target algebra. This talk will give details of the theorem, this corollary and their proofs.
