Abstract:
In this talk,we show that if every unital separable C*-algebra has a completely bouded representation in von Neumann algebra which has the Kirchberg's quotient weak expectation property（QWEP）,then this represention is similar the * reptesentation. Eberhard Kirchberg showed that every von Neumann algebra has QWEP if and only if every tracial von Neumann algebra can be embeded into the ultrapower algbra of hyperfinite factor(Which just is famous Connes' embedding problem). Furthermore We provide a negative answer to the Connes' embedding problem.
