We compare some alternative topological assumptions in a Levin's type theorem, and show that they are equivalent to a Polish space assumption.Reconocimiento - No comercial - Sin obra derivada (by-nc-nd)Preorder normalityUtilitiesPreorder representationsk-spaces89Topological conditions for the representation of preorders by continuous utilitiesArtÃculo2017-09-1310.4995/agt.2012.1640Abierto1989-4147
