Representing preorders with injective monotones. [PDF]

Theory Decis, 2022
AbstractWe introduce a new class of real-valued monotones in preordered spaces, injective monotones. We show that the class of preorders for which they exist lies in between the class of preorders with strict monotones and preorders with countable multi-utilities, improving upon the known classification of preordered spaces through real-valued ...

Almost quasi-Urbanik structures and theories

Қарағанды университетінің хабаршысы. Математика сериясы
The notions of almost quasi-Urbanik structures and theories, and studied possibilities for the degrees of quasi-Urbanikness, both for existential and universal cases were introduced. Links of these characteristics and their possible values are described.

Structures on the space of financial events

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2008
In this paper we endow the space of financial events with some structures, each of them represents basic facts of financial mathematics. We introduce a preordered structure, that we shall call the usual preorder of the financial events plane, and an ...

Derivations of Incidence Algebras

Mathematics
We study the derivations of the incidence algebra I(X,R), where X is a preordered set and R is an algebra over some commutative ring T. A satisfactory description of the T-module of derivations and the T-module of outer derivations of this algebra is ...

Continuous Multi-Utility Representations of Preorders and the Chipman Approach

Axioms
Chipman contended, in stark contrast to the conventional view, that, utility is not a real number but a vector, and that it is inherently lexicographic in nature.

Regular and urgent ordering with lateral transshipment in a distribution network with stochastic pre-ordered and peddling demands

Asian Journal of Shipping and Logistics
We propose inventory replenishment and lateral transshipment policies for a distribution network. The distribution centers place weekly regular orders and daily urgent orders to the factory.
