Bicentralizer conjecture for inclusions with expectations

About 3 years old · traced to

Let N⊂MN \subset M be an inclusion of von Neumann algebras with expectations. For a strictly semifinite weight φ∈P(N)\varphi \in \mathcal{P}(N), let B(N⊂M,φ)\mathord{\mathrm{B}}(N \subset M,\varphi) and b(N⊂M,φ)\mathord{\mathrm{b}}(N \subset M,\varphi) denote the two bicentralizer algebras defined in the paper. Bicentralizer conjecture.

B(N⊂M,φ)=b(N⊂M,φ)\mathord{\mathrm{B}}(N \subset M,\varphi)=\mathord{\mathrm{b}}(N \subset M,\varphi)

for every strictly semifinite weight φ∈P(N)\varphi \in \mathcal{P}(N). This is the paper's general bicentralizer assertion for inclusions with expectations; the supplied candidate carries no resolution evidence, so its full status remains open.
