Sublinear and Continuous Order-preserving Functions for Noncomplete Preorders
نویسندگان
چکیده
We characterize the existence of a nonnegative, sublinear and continuous order-preserving function for a not necessarily complete preorder on a real convex cone in an arbitrary topological real vector space. As a corollary of the main result, we present necessary and sufficient conditions for the existence of such an order-preserving function for a complete preorder.

Numerical Representability of Ordered Topological Spaces with Compatible Algebraic Structure
We analyze the numerical representability of total preorders defined on semitopological real algebras through continuous order-preserving real-valued functions that are also additive and multiplicative. The results obtained are used to interpret important concepts arising in Social Choice theory.
متن کاملTopologies Corresponding to Continuous Representability of Preorders
A topology τ on a fixed nonempty set X is said to satisfy the weakly continuous representation property if every weakly continuous not necessarily total preorder on the topological space (X, τ) admits a continuous order preserving function. Such a property generalizes the well known continuous representation property of a topology τ on a set X (according to which every continuous total preorder...

متن کاملFuzzy order congruences on fuzzy posets
Fuzzy order congruences play an important role in studying the categoricalproperties of fuzzy posets. In this paper, the correspondence between the fuzzyorder congruences and the fuzzy order-preserving maps is discussed. We focus onthe characterization of fuzzy order congruences on the fuzzy poset in terms ofthe fuzzy preorders containing the fuzzy partial order. At last, fuzzy completecongruen...
متن کاملTailoring Filter Models
Conditions on type preorders are provided in order to characterize the induced filter models for the λ-calculus and some of its restrictions. Besides, two examples are given of filter models in which not all the continuous functions are representable.
