The classification of flows on $II_{1}$ factors and Connes' bicentralizer problem

Cyril Houdayer, Amine Marrakchi

We settle two long-standing open problems in von Neumann algebras. First, we show that every outer flow with full Connes spectrum on the hyperfinite $II_{1}$ factor has the…

Uniqueness of almost periodic outer flows on the hyperfinite type $II_{1}$ factor

Cyril Houdayer, Amine Marrakchi

We show that any almost periodic outer flow $α : R ↷ R$ on the hyperfinite type $II_{1}$ factor with Connes' spectrum $Γ (α) = R$ satisfies the…
