【正文】 xioms are required for a utility function to exist: (1) The relation is reflexive: a ? a (2) The relation is transitive: a ? b and b ? c then a ? c. (3) The relation is plete: for all a and b in S, a ? b or b ? a or both. (4) The relation is continuous (if S is a topological space, then for each point x in S, the set of points that are strictly preferred to x and the set of points that x is strictly preferred to are both open).
