摘      要: The standard notion of morphisms between operator algebras is (*-)homomorphisms. A more general notion called c.p.c. order zero maps was introduced by W. Winter and J. Zacharias. Extensive theories have been built on top of this notion, including various dimensions for C*-algebras and C*-dynamical systems. It has played a pivotal role in the classification program of C*-algebras and is seeing more applications to C*-dynamical systems and quantum principal bundles. I will survey some of the ideas and results around this notion.
