Abstract

We study certain densely defined unbounded operators on the Segal– Bargmann space. These are the annihilation and creation operators of quantum mechanics. In several complex variables we have the ∂-operator and its adjoint ∂

acting on (p, 0)-forms with coefficients in the Segal–Bargmann space. We consider the corresponding ∂-complex and study the spectral properties of the corresponding complex Laplacian ˜□ = ∂∂

+ ∂

∂. Finally, we study a more general complex Laplacian ˜□

D = DD

+ D

D, where D is a differential operator of polynomial type, to find the canonical solutions to the inhomogeneous equations Du = α and D

v = β.
