I am wondering about the formal definitions of the dot-product and dirac brackets <>. Of course <> brackets apply equally to functions as well as vectors (in Hilbert space).
Is it safe to assume that . and <> are equivalent?
Can one state that <a|b> equivalent to |a| |b| cosT where a and b are n dimensional vectors? (I assume that even in N space any pair of vectors has only 1 angle between them)
I see various material about this on the internet but not always consistent. Some of my texts ignore talking about it!
Thanks-fritz
