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.

Notes

  1. 1.

    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 \(\mathfrak{v}_{n} \cap \upkappa _{0} =\{ 0\}\).

  2. 2.

    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].
