Title:Linear differential operators on contact manifolds
Seminar:GAP Seminar
Speaker:Valentin Ovsienko, University of Lyon 1
Abstract:
(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.
