Un cadre pour les espaces localement structurés - application aux modèles géométriques de la concurrence

, 2022
The usage of methods from Algebraic Topology in the study of concurrent processes was initiated in 1998. One of its key ingredient is the realization of precubical sets in the category of locally ordered spaces.

Pretorsion theories

, 2021
Pretorsion theories∗ The notion of pretorsion theory is a wide extension of the classical notion of torsion theory in an abelian category. The idea is to associate, with any pair (T, F) of full replete subcategories of a category C, a corresponding ...

Cartesian closed hull for (quasi-)metric spaces (revisited) [PDF]

, 2000
summary:An existing description of the cartesian closed topological hull of $p\text{\bf MET}^\infty$, the category of extended pseudo-metric spaces and nonexpansive maps, is simplified, and as a result, this hull is shown to be a special instance of a ...

Preordered topological spaces, utility and jointly utility functions

, 2012
Classical theorems of Eilenberg and Debreu state that every continuous total order, defined respectively on a connected separable space and on a second countable space, has a continuous representation.

Über die Stetigkeit einer Funktion von zwei Veränderlichen unter Monotonie-Bedingungen

, 1991
Let T, E, F be topological spaces, and let E, F also be preordered with some compatibility between topology and order stucture. Theorem: If f(t,x): T×E→F is separately continuous with respect to its variables and monotone non-decreasing with respect to x,

Existence of continuous utility functions for arbitrary binary relations: some sufficient conditions

We present new sufficient conditions for the existence of a continuous utility function for an arbitrary binary relation on a topological space. Such conditions are basically obtained by using both the concept of a weakly continuous binary relation on a ...
