A simple characterization of the existence of upper semicontinuous order-preserving functions [PDF]
Economic Theory Bulletin, 2023 AbstractWe introduce an upper semicontinuity condition concerning a not necessarily total preorder on a topological space, namely strong upper semicontinuity, and in this way we extend to the nontotal case the famous Rader’s theorem, which guarantees the existence of an upper semicontinuous order-preserving function for an upper semicontinuous total ...

Order-preserving functions: Applications to majorization and order statistics [PDF]
Pacific Journal of Mathematics, 1967 Abstract : It has been common in the theory of reliability and its practice to assume that the life of a device is exponentially distributed (i.e. it has constant hazard or failure rate) or intuitively, that the device does not wear in service. This assumption is mathematically convenient, but it should not be employed without verification of its ...

Numerical representability of fuzzy total preorders [PDF]
International Journal of Computational Intelligence Systems, 2012 We introduce the concept of a fuzzy total preorder. Then we analyze its numerical representability through a real-valued order-preserving function defined for each -cut.

Results in Physics, 2023 While there is a growing consensus that lattice is an important source of entropy change at structural or elastic first-order magnetic transitions (FOMT) with finite volume change, the case of volume preserving transitions (ΔV = 0) remains more ...

From nominal to higher-order rewriting and back again [PDF]
Logical Methods in Computer Science, 2015 We present a translation function from nominal rewriting systems (NRSs) to combinatory reduction systems (CRSs), transforming closed nominal rules and ground nominal terms to CRSs rules and terms, respectively, while preserving the rewriting relation. We

Order-preserving minimal perfect hash functions and information retrieval [PDF]
ACM Transactions on Information Systems, 1989 Rapid access to information is essential for a wide variety of retrieval systems and applications. Hashing has long been used when the fastest possible direct search is desired, but is generally not appropriate when sequential or range searches are also required.

Dissipativity preserving model reduction by retention of trajectories of minimal dissipation [PDF]
, 2009 We present a method for model reduction based on ideas from the behavioral theory of dissipative systems, in which the reduced order model is required to reproduce a subset of the set of trajectories of minimal dissipation of the original system.

On order-preserving and order-reversing mappings defined on cones of convex functions [PDF]
Science China Mathematics, 2021 In this paper, we first show that for a Banach space $X$ there is a fully order reversing mapping $T$ from ${\rm conv}(X)$ (the cone of all extended real-valued lower semicontinuous proper convex functions defined on $X$) onto itself if and only if $X$ is reflexive and linearly isomorphic to its dual $X^*$.
