LetXbe a compact connected CR manifold of dimensionwith a transversal CR-action onX. We study the Fourier components of the Kohn–Rossi cohomology with respect to the-action. By studying the Szegö kernel of the Fourier components we establish the Morse inequalities onX. Using the Morse inequalities we have established onXwe prove that there are abundant CR functions onXwhenXis weakly pseudoconvex and strongly pseudoconvex at a point.
