Understanding the problem

Read the background

Every type II₁ factor with separable predual is generated as a von Neumann algebra by one bounded operator, equivalently two self-adjoint operators.

Why it matters

If correct, resolves the generator problem for type II₁ factors with separable predual and, with the established reduction, for all von Neumann algebras with separable predual.

What counts as progress

Can every type II₁ factor with separable predual be generated by one operator?
