Claims

C1strongest claim

the contradiction underlying Condorcet's Paradox topologically corresponds to the non-orientability of a surface homeomorphic to either the Klein Bottle or Real Projective Plane, depending on how preference cycles are represented

C2weakest assumption

that the chosen topological representation of preference cycles (generalizing Baryshnikov's model for strict ordinal preferences on three alternatives) faithfully captures the logical contradiction without introducing extraneous structure

C3one line summary

Condorcet's paradox corresponds to non-orientability of a surface homeomorphic to the Klein bottle or real projective plane in a generalized topological model of strict ordinal preferences.
