Abstract:
We consider analytic differential operators of order n defined on
two-dimensional manifolds. Namely, linear operators locally of the
form:
Sum_{0<=i+j<=n} f_{ij} (d/dx)^i (d/dy)^j,
with f_{ij} analytic functions. After introducing the notion of elementary
singular point for such operators, we discuss a theorem of resolution of
singularities, generalizing the classical result of Bendixson-Seidenberg
for vector fields in dimension two.
