A modification of Poincare's construction and its application to the CR geometry of hypersurfaces in
V. K. Beloshapka
A generalization of the homological Poincare's operator was used to estimate the dimension of the Lie algebra of infinitesimal holomorphic automorphisms of an arbitrary germ of a r…

Homogeneous hypersurfaces in $\CC{3}$, associated with a model CR-cubic
V. K. Beloshapka, I. G. Kossovskiy
The model 4-dimensional CR-cubic in $\CC{3}$ has the following "model" property: it is (essentially) the unique locally homogeneous 4-dimensional CR-manifold in $\CC{3}$ with finit…
