Then the group G = O(p + 1, q + 1) acts as conformal diffeomorphisms on [S.sup.p] x [S.sup.q], and also on its quotient space X = ([S.sup.p] x [S.sup.q])/[Z.sub.2] by identifying the direct product of antipodal points. By the general theory of conformal groups, one has a natural family of representations [[??].sub.[lambda]] on [C.sup.[infinity]](X) with parameter [lambda] [member of] C [12, Sect.
