Deforming the Lie algebra of vector fields on inside the Lie algebra of pseudodifferential symbols on
C. Roger, V. Ovsienko
We classify nontrivial deformations of the standard embedding of the Lie algebra $\Vect(S^1)$ of smooth vector fields on the circle, into the Lie algebra~$\PD(S^1)$ of pseudodiffer…
Lorentzian worldlines and Schwarzian derivative
C. Duval, V. Ovsienko
We relate in this note the classical Schwarzian derivative to the curvature of time-like curves in Lorentz surfaces of constant curvature.
Projectively equivariant symbol calculus
P. B. A. Lecomte, V. Yu. Ovsienko
The spaces of linear differential operators on acting on tensor densities of degree and the space of functions on which are polynomial on t…
Conformally equivariant quantization
C. Duval, V. Ovsienko
Let be a pseudo-Riemannian manifold and the space of densities of degree on . We study the space of second-order differential operators from…
