OpenAI reports expected amenable subalgebras preserving core commutants

For every unital expected inclusion N⊂M of von Neumann algebras with separable preduals, there is an expected unital amenable subalgebra P⊂N with P′∩c(M)=N′∩c(M), where c(M) is the continuous core.

Read the background

For every unital expected inclusion N⊂M of von Neumann algebras with separable preduals, there is an expected unital amenable subalgebra P⊂N with P′∩c(M)=N′∩c(M), where c(M) is the continuous core.

Why it matters

If correct, resolves the relative bicentralizer conjecture for expected inclusions with separable preduals.

What counts as progress

Can an expected amenable subalgebra preserve an inclusion’s relative commutant in the continuous core?
