Bin Gui (Tsinghua University)
A modern point of view on Antony Wassermann's paper "Operator Algebras and Conformal Field Theory III" (English)
[ Abstract ]
In 1998, Antony Wassermann's groundbreaking paper "Operator Algebras and Conformal Field Theory III" was published. This paper calculated Connes fusion rules for the representations of type A WZW conformal nets and was essential to many subsequent works on conformal nets. In this talk, I will try to convince the audience that many of Wassermann's ideas are powerful for understanding VOA/Conformal net correspondence in the framework of Carpi-Kawahigashi-Longo-Weiner and Tener.
