> Abstract: Marengo, Pasquali and Settepanella present a model of object
> construction in majority voting and show that, in general, by appropriate
> changes of such bundles, different social outcomes may be obtained.
> They construct a model of individual preferences and social aggregation
> based on hyperplane arrangements. By using this model they prove their
> assertions retrieving also a generalization of the Arrow's
> Impossibility Theorem.
