A Hincin Type Characterization of Infinite Divisibility for
Operator Valued Free Probability
Monday, October 24 3pm, 646 PGH
Abstract
Operator valued free probability theory was developed in the
1990's as a method of encoding amalgamated free product phenomenon in
operator algebras in a probabilistic setting. As in the case of scalar
valued free probability, this theory may be developed along similar lines
as classical probability theory, with many classical theorems having free
analogues.
In classical probability theory, it was proven by Hincin that a
probability measure that is the weak limit of the convolution of an
infinitesimal array of probability measures is necessarily infinitely
divisible. We will provide an alternative proof of this theorem utilizing
the Steinitz Lemma. We will then use this approach to prove an analogous
result in the field of operator valued free probability theory.
