Arveson's essential normality conjecture for quotient Bergman modules

About 13 years old · traced to

Let Ω⊆Cm\Omega\subseteq\mathbb{C}^m be a bounded strongly pseudoconvex domain with smooth boundary, let AA be the algebra of analytic functions under consideration, and let II be an ideal in AA. Write I⊥=La2(Ω)⊖I‾I^{\perp}=L^2_a(\Omega)\ominus\overline{I}, and let

Tp=PI⊥Mp∣I⊥,p∈A,T_p=P_{I^{\perp}}M_p|_{I^{\perp}},\qquad p\in A,

be the compressed multiplication operators. The module I⊥I^{\perp} is essentially normal when all commutators of its fundamental tuple are compact. Arveson's conjecture. I⊥I^{\perp} is essentially normal. In other words, all commutators

[Tzj,Tzk∗],j,k=1,…,m,[T_{z_j},T_{z_k}^{*}],\qquad j,k=1,\ldots,m,

are compact. This conjecture asks for essential normality of quotient modules arising from ideals in Bergman spaces and is part of the operator-theoretic study of algebraic varieties and their boundary geometry. The supplied text does not state whether it has been resolved.
