摘要
We show that the spectrum (A) over cap of a separable C*-algebra A is discrete if and only if A*, the Banach space dual of A, has the weak* fixed point property. We prove further that these properties are equivalent among others to the uniform weak* Kadec-Klee property of A* and to the coincidence of the weak* topology with the norm topology on the pure states of A. If one assumes the set-theoretic diamond axiom, then the separability is necessary.
