Nachuntersuchung und ManualbefundePositive elements play a very important role in the theory of C*-algebras. They allow us to define a partial order on the self-adjoint elements which is a key part of the structure of any C*-algebra.

Nachuntersuchung und ManualbefundeIn this section we will see that every abstract C*-algebra is *-isomorphic to a self-adjoint closed subalgebra of B(H), for some Hilbert space H. That is to say, the class of abstract C*-algebras and the class of concrete C*-algebras coincide.

Nachuntersuchung und ManualbefundeWe have seen that C*-algebras boast a number of good structural properties that distinguish them from arbitrary Banach algebras. There are various types of maps one could consider between C*-algebras which aim at preserving particular C*-algebraic properties.
