A study of a certain non-conventional operator of principal type. II (Q1080159)

We continue our study of the operator \[ B^ I=D_ t+\sqrt{-1}(t^ 2/2+x)D_{\nu}, \] \(D_ t=-\sqrt{-1}\partial /\partial t\), \(D_{\nu}=- \sqrt{-1}\partial /\partial y\), in (a neighbourhood of the origin in) \({\mathbb{R}}^ 3\). Here we discuss solvability of the equation: \(B^ Iu=f\) for a given f. [For part I see the review above].
