Abstract
We discuss the relationship between groups of CR cohomology of some compact homogeneous CR manifolds and the corresponding Dolbeault cohomology groups of their canonical embeddings.

In fact, if \(\bar{Z} \in \bar{\mathfrak{v}}_{n}\), then \(\bar{Z} = -Z + (Z +\bar{ Z})\), with \(Z =\bar{\bar{ Z}} \in \mathfrak{v}_{n}\) and \(Z +\bar{ Z} \in \upkappa _{0}\). The sum is direct because \(\mathfrak{v}_{n} \cap \upkappa _{0} =\{ 0\}\).

Actually they consider a slightly less restrictive condition, which is related to a notion of weak CR-degeneracy for homogeneous CR manifolds that was introduced in [22].
