Abstract

The simplest linear partial differential equations whose local solvability is not automatic are those defined by complex, smooth, nowhere vanishing vector fields in regions of the plane. Let \(L = A\left( {{x_1},{x_2}} \right)\partial /\partial {x_1} + B\left( {{x_1},{x_2}} \right)\partial /{\partial _2} \) be such a vector field, defined in a domain Ω ⊂ R 2. The (inhomogeneous) equation
$$Lu = f$$
(1)
is said to be locally solvable at a point O ∈ Ω if there is an open neighborhood U ⊂ Ω of O such that, given any fC (Ω), there is a distribution uD′(U) that satisfies (1) in the open set U. One can vary this definition by asking that u be a C function, in which case one may talk of local solvability in C ; or by asking that there be a distribution solution u in U, for each fD′(Ω). A moment of thought will also show that there is no loss of generality if we restrict our attention to right hand sides f whose support is compact and contained in U.
