What is The classification problem for von Neumann factors about?
We prove that it is not possible to classify separable von Neumann factors of types II 1 , II ∞ or III λ , 0 λ 1, up to isomorphism by a Borel measurable assignment of "countable structures" as invariants. In particular the isomorphism relation of type II 1 factors is not smooth. We also prove that the isomorphism relation for von Neumann II 1 factors is analytic, but is not Borel.
Who reads The classification problem for von Neumann factors?
It is typically read by researchers, students, and practitioners in Mathematics.
