AbstractIn this article we study the problem --EQUATION OMITTED-- in the case Ωa is an expanding domain. In particular, for n⩾2 when Ωa={x∈Rn:a<|x|<a+1} is an expanding annulus as a→∞, we prove the existence of many rotationally non-equivalent solutions obtained as local minimizers of the corresponding energy functional. Moreover, we study the exact symmetry and the shape of these solutions, and under certain conditions we prove the existence of solutions with prescribed symmetry
