We refine the analysis of Chichilnisky [Chichilnisky, G., The topological equivalence between the Pareto condition and the existence of dictator, J. Math. Econ. 9 (1982) 223–233] and Koshevoy [Koshevoy, G., Homotopy Properties od Pareto Aggregation Rules, 1993, preprint] of the topology of continuou...
