Ordinal utility functions are unique up to increasing monotone (or monotonic) transformations. The resulting algorithm is therefore invariant with respect to monotonic transformations of the objective function. These make the analysis focus on symmetric and monotonic bidding strategies. Thus the axioms so far have all been for monotonic Boolean logic. In the monotonic standard orthography, subscript iota is not used. The class of all preordered sets with monotonic functions as morphisms forms a category, Ord. The set of discontinuities of a monotonic function is at most countable. Since "g"("x") is strictly monotonic and continuous, it is a homeomorphism. Let formula 12, and let formula 13 be either convex or monotonic. Only the glyphs used in monotonic orthography are available. They are usually monotonic and quasi-concave. ISO 8859-7 supports only the monotonic orthography; Unicode supports both the monotonic and polytonic orthographies. The state progression is a monotonic function. Milgrom pioneered in the development of new mathematical methods for understanding monotonic relationships in economics. This is a special case of the more general notion of a monotonic function.
