“…Throughout this section, we review some of basic results concerning abstract harmonic analysis over spaces of complex measures on coset spaces of compact subgroups in locally compact groups, for details and proofs see [11,15]. Also, it is still assumed that G is a locally compact group, H is a compact subgroup of G, and µ is the normalized G-invariant measure over the left coset space G/H associated to (2.9) with respect to the fixed left Haar measure dx = dσ(x) of G and the probability measure of H. It should be mentioned that, from now on by a complex measure we mean a regular countably additive complex Borel measure.…”
