Resumen de Normally preordered spaces and continuous multi-utilities

Gianni Bosi , Alessandro Caterino, Rita Ceppitelli

• We study regular, normal and perfectly normal preorders by referring to suitable assumptions concerning the preorder and the topology of the space. We also present conditions for the existence of a countable continuous multi-utility representation, hence a Richter-Peleg multi-utility representation, by assuming the existence of a countable net weight.
