|Title:||Linear differential operators on contact manifolds|
|Speaker:||Valentin Ovsienko, University of Lyon 1|
|(Joint with Charles Conley) We consider differential operators between sections of arbitrary powers of the determinant line bundle over a contact manifold. Our main result is an intrinsically defined "subsymbol" of a differential operator, which is a differential invariant of degree one lower than that of the principal symbol. In particular, this subsymbol associates a contact vector field to an arbitrary second order linear differential operator.|
