Combinatorial Theory of the Free Product with Amalgamation and Operator-Valued Free Probability Theory
Share this pageRoland Speicher
Free probability theory, introduced by Voiculescu, has
developed very actively in the last few years and has had an
increasing impact on quite different fields in mathematics and
physics. Whereas the subject arose out of the field of von Neumann
algebras, presented here is a quite different view of Voiculescu's
amalgamated free product. This combinatorial description not only
allows re-proving of most of Voiculescu's results in a concise and
elegant way, but also opens the way for many new results.
Unlike other approaches, this book emphasizes the combinatorial
structure of the concept of “freeness”. This gives an elegant and
easily accessible description of freeness and leads to new results in
unexpected directions. Specifically, a mathematical framework for
otherwise quite ad hoc approximations in physics emerges.
