Suppose that u is a bounded harmonic function on the upper half-plane such that for some y0>0. Then one can prove that for any other positive y. In this paper, we shall consider the algebra of radial integrable functions on H-type groups and obtain a similar result for bounded harmonic functions on generalized Siegel domains.
