Abstract: Since the 50's of the last century, Eckman observed that the existence of n-medias over certain topological spaces (polyhedra) is closely related to its homotopic structure. He uses the functors of homotopy and singular homology groups to characterize compact polyhedra that have an n-media. Surprisingly, and independently of Professor Eckman, economists Chichilnisky and Heal use these same techniques in the 1980s to solve problems arising from social choice theory. In this talk I will show the functors between certain categories that are derived from Top and Grp that I have used in obtaining recent results on social choice functions.
