Schedule: The conference begins on Monday, 9 June at 9:30. It ends on Friday at 12:50. Here is the detailed schedule and the abstracts.

Location: All lectures (except for the official colloquium) take place in lecture hall HS III, building E2 5, Saarland University, Saarbrücken, Germany. (PDF map of the campus, interactive map)

Goal:  Since its initiation in the 1980s by Voiculescu, free probability theory has always been expanding and today it is as timely as ever. It is linked to theoretical fields such as operator algebras, representation theory of groups and quantum information theory but also to more applied fields such as random matrix theory, wireless communications and various others. The common themes are noncommutativity of certain variables and the description of an asymptotical behaviour.
The aim of the conference is to bring together leading experts in free probability theory in order to exchange recent developments, survey the broadness of the field and to explore new directions.

We dedicate this conference to Roland Speicher on the occasion of his 65th birthday. We recall his vast contributions to free probability, such as his work on a combinatorial approach to freeness using cumulants and partitions of sets, free central limit theorems, universal products, R-diagonal operators, second order freeness, operator-valued free probability, free Brownian motion, q-Gaussians, Boolean convolution, fourth moment theorems and de Finetti theorems, just to name a few. 
Undoubtedly, Roland Speicher has been one of the founding fathers of free probability theory, he has always been a central player in the development, broadening and community building of the field and he is still one of the key figures in the domain. 
With this conference, we intend to express our appreciation for Speicher's life long efforts for the field and we aim at contributing to a continuation of his personal work on free probability as well as to keep his spirit alive that free probability should be open to influences and interactions with many other fields.
