  In this note we construct bi-*-Galois objects linking the quantized universal
enveloping algebras associated to the Lie groups SU(2), E(2) and SU(1,1), where
E(2) denotes the Lie group of Euclidian transformations of the plane, and we
show how one can create (formal) quantum homogeneous spaces for these quantum
groups by integrating the associated Miyashita-Ulbrich action on certain
subquotient *-algebras.
