If the optima set for the social preference relation σ(u) is non-empty, and for a sufficiently small “perturbation” u’ of the profile u, the optima set for σ(u’) is still non-empty then we shall say the optima set is ..

Local Cycles,mpty and cycles may occur when the set W is discrete and of cardinality v(σ), wes now demonstrate that voting cycles may be constructed in dimension v(σ)—1 or above. Indeed we shall show that a σ-permutation profile exists in this dimension. In parallel to the finite case, the existence of this kind
