Abstract:LetG be a compact group of automorphism acting continuously on a compact groupH. Then the orbit spaceH G is a compact hypergroup. We characterize, all solvable groupsH and compact automorphism groupsG for whichH G is almost discrete, i.e.,H G is homeomorphic to the one-point-compactification of Nopf. It turns out that thenH is isomorphic either to the infinite direct product Zopf(p)Nopf of the cyclic groups Zopf(p) or to Nopf p n (Zopf p the group of allp-adic numbers) for some primep and some Nopf. The almost discrete orbit hypergroupsH G are determined explicitly for some examples.
