Resumen de Cones arising from C*-subalgebras and complete positivity

Florin Pop, Roger R. Smith

• Let B A be an inclusion of C*-algebras. Then B is said to norm A if, for each X (A), In this paper we introduce and study the cones These are shown to coincide with the standard positive cones precisely when B norms A, and we apply this to obtain automatic complete positivity of certain positive maps between C*-algebras
