Abstract: | The Euclidean distance technique of Arrow and Hahn is used to construct an upper semicontinuous order homomorphism (partial utility function) from (X, ≻) to (, >), where X is a closed, convex subset of N and ≻ is a continuous strict partial order on X. It is also shown that the order homomorphism is upper semicontinuous as a function on , where is the set of continuous strict partial orders on X, taken with the topology of closed convergence. |
