Free probability is a quite young mathematical theory with many avatars.
It started in the theory of operator algebras, showed its beautiful combinatorial
structure via non-crossing partitions, made contact with the world of random
matrices, and reached out to many other subjects like representation theory of large
groups, quantum groups, invariant subspace problem, large deviations, quantum
information theory, subfactors, or statistical inference. Even in physics and engineering,
people have heard of it and find it useful and exciting.
This course is in a sense a continuation of both the classes “Random Matrices” and “Operator Algebras” from the summer term 2018, as it deals with the concept of “freeness” or “free independence”, which appears both in the limit of random matrices as well as for important classes of von Neumann algebras. On the other hand, freeness is an important concept for its own sake which deserves to be investigated independently of its random matrix or operator algebraic roots. That’s what we will do in this course; we will, in particular, look at the combinatorial, analytical and probabilistic structure of freeness.
