Type Preorders and Recursive Terms

open access: yesElectronic Notes in Theoretical Computer Science, 2005
AbstractWe show how to use intersection types for building models of a λ-calculus enriched with recursive terms, whose intended meaning is of minimal fixed points. As a by-product we prove an interesting consistency result.

The stable category of preordered groups

open access: yes, 2023
In this article, we present the stable category of preordered groups associated with some Z-pretorsion theory. We first define such a category as well as the related functor, and then study their properties.

Optimizing Unmanned Aerial Vehicle Battery Management for Energy‐Aware Mapping Missions

open access: yesInternational Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
Unmanned aerial vehicles are widely used for mapping and surveillance applications. A challenging task in mission planning is managing battery use, especially when mapping large areas in a single operation. Mission planning in this case leads to an optimization problem that is generally computationally demanding and intractable in practice.

A Logical Characterization of Efficiency Preorders [PDF]

open access: yes, 2005
In this paper we present logical characterizations of two preorders, within the framework of Hennessy-Milner Logics. The two preorders (loosely termed bisimulation-based efficiency preorders) are on processes represented as labelled transition systems. The characterizations are particularly interesting as they explore preorders lying between strong and

Almost quasi-Urbanik structures and theories

open access: yesҚарағанды 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

open access: yesAtti 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 ...

“It's a tough job, but somebody's got to do it”: Committed consumers' voluntary emotion work in alternative market systems

open access: yesJournal of Consumer Psychology, Volume 35, Issue 4, Page 584-601, October 2025.
Abstract Despite increasing attention to alternative market systems, where consumers perform considerable voluntary labor, consumer researchers have a limited understanding of the nature or implications of the emotion work entailed in making such contributions.

Pretorsion theories, stable category and preordered sets

open access: yes, 2020
We show that in the category of preordered sets there is a natural notion of pretorsion theory, in which the partially ordered sets are the torsion-free objects and the sets endowed with an equivalence relation are the torsion objects.
