Non-commutative probability I: Operator algebras background
 

Summary: Non-commutative probability I:
Operator algebras background
Michael Anshelevich
November 21, 2002
Let (A, ) be a non-commutative probability space.
A =-algebra with identity,
(a + b) = a + b; (ab) = ba.
= linear functional A C, a state, i.e. positive
aa 0,
unital
[1] = 1.
A is a C-algebra, has a norm such that
ab a b , a = a ,
and
aa = a 2
.
= norm-continuous.

Example . Let be a compact set, then A = C(, C)
is a C-algebra with complex conjugation f = f and
