Abstract
We consider the solution operator S: ℱμ,(p,q) → L 2(μ)(p, q) to the \({\bar \partial }\)-operator restricted to forms with coefficients in ℱμ = {f: f is entire and ∫ℂn |f(z)|2 dμ(z) < ∞}. Here ℱμ,(p,q) denotes (p,q)-forms with coefficients in ℱμ, L 2(μ) is the corresponding L 2-space and μ is a suitable rotation-invariant absolutely continuous finite measure. We will develop a general solution formula S to \({\bar \partial }\). This solution operator will have the property Sv ⊥ ℱ(p,q) ∀v ∈ ℱ(p,q+1). As an application of the solution formula we will be able to characterize compactness of the solution operator in terms of compactness of commutators of Toeplitz-operators \([T_{\overline {z_i } } ,T_{z_i } ] = [T_{z_i }^* ,T_{z_i } ]\): ℱμ → L 2(μ).
