Abstract

Given a compact (Hausdorff) group GG and a closed subgroup HH of G,G, in this paper we present symbolic criteria for pseudo-differential operators on compact homogeneous space G/HG/H characterizing the Schatten-von Neumann classes Sr(L2(G/H))S_r(L^2(G/H)) for all 0<r.0<r \leq \infty. We go on to provide a symbolic characterization for rr-nuclear, 0<r1,0< r \leq 1, pseudo-differential operators on Lp(G/H)L^{p}(G/H)-space with applications to adjoint, product and trace formulae. The criteria here are given in terms of the concept of matrix-valued symbols defined on noncommutative analogue of phase space G/H×G/H^.G/H \times \widehat{G/H}. Finally, we present applications of aforementioned results in the context of heat kernels.
