Deforming the Lie algebra of vector fields on $S^{1}$ inside the Lie algebra of pseudodifferential symbols on $S^{1}$

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…
