I'd like to better understand states on C*-algebras.
What properties should I investigate and in which order?
(Positive functionals, extremal states, Schwarz's inequality, Kadison's inequality, what else?)
I suppose basic facts about functional analysis.
(C*-algebras, spectral theory, functional calculus, Banach-Alaoglu, etc.)
Thanks alot for your ideas!! :)
Just if somebody is interested...
I found the book by Zhu: An Introduction to Operator Algebras.
It just fits quite nicely when trying to get a first touch with the subject.
