Abstract

We compute the spectra of the Tanaka type Laplacians on the Rumin complex, a quotient of the tangential Cauchy-Riemann complex on the unit sphere in CnC^n. We prove that Szeg\"o map is a unitary operator from a subspace of (p,q1)(p, q-1)-forms on the sphere defined by the Tanaka operators and the normal vector field onto the space of L2L^2-harmonic (p,q)(p, q)-forms on the unit ball. Our results generalize earlier result of Folland.
