DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QGS/48/">A m
 etric characterization of freeness</a>\nby Benoît Collins (Kyoto Universi
 ty\, Japan) as part of Quantum Groups Seminar [QGS]\n\n\nAbstract\nFreenes
 s of random variables has many characterizations\, with free cumulants\, f
 ree entropy\, Schwinger-Dyson equations\, etc. Here\, we discuss a new met
 ric characterization with the norm of the sum of generators tensored by th
 eir adjoint\, and explain the relation and applications to other problems 
 in operator algebras and von Neumann algebras. Time permitting\, we will a
 lso discuss some ingredients of the proof. This is based on joint work wit
 h Leonard Cadilhac.\n
