Query: Singular deformations of Lie algebras on an example   The notion of singular one-parameter deformation of a Lie algebra is
introduced. It is shown that the complex infinite-dimensional Lie algebra of
polynomial vector fields in C with trivial 1-jet at the origin has such
singular deformation.
