Probability and algorithmics: a focus on some recent developments
2017
Jean-François Coeurjolly, Adeline Leclercq-Samson Eds.; International audience; This article presents different recent theoretical results illustrating the interactions between probability and algorithmics. These contributions deal with various topics: cellular automata and calculability, variable length Markov chains and persistent random walks, perfect sampling via coupling from the past. All of them involve discrete dynamics on complex random structures.; Cet article présente différents résultats récents de nature théorique illustrant les interactions entre probabilités et algorithmique. Ces contributions traitent de sujets variés : automates cellulaires et calculabilité, chaînes de Mark…
Coding Partitions
2007
Motivated by the study of decipherability conditions for codes weaker than Unique Decipherability (UD), we introduce the notion of coding partition. Such a notion generalizes that of UD code and, for codes that are not UD, allows to recover the ''unique decipherability" at the level of the classes of the partition. By tacking into account the natural order between the partitions, we define the characteristic partition of a code X as the finest coding partition of X. This leads to introduce the canonical decomposition of a code in at most one unambiguous component and other (if any) totally ambiguous components. In the case the code is finite, we give an algorithm for computing its canonical…
A note on Hilbert’s weak nullstellensatz
2015
In this article, through a suitable generalization of the well-known notion of spectrum of an element of an arbitrary normed algebra of Operator Theory, it will be possible to give another simple proof of the Hilbert’s Weak Nullstellensatz.

Liber aureus: mélanges d'Antiquité et de contemporanéité offerts à Nicole Fick
2012
International audience; Liber aureus, dont le titre pastiche celui d’un des romans latins sur lesquels la dédicataire a tant travaillé, est un recueil d’articles offerts à Nicole fick par les nombreux collègues qui, par-delà sa retraite, gardent d’elle un vif et plaisant souvenir. Conformément à la curiosité intellectuelle de Nicole Fick, ces articles s’intéressent bien sûr au roman antique et à l’Antiquité en général, mais aussi à la survivance de l’Antiquité et à quelques autres domaines de la recherche
Construction of quality indicators based on pre-established goals: application to a colombian public university
2020
This study creates indicators of adequacy and excellence based on multiple-criteria decision-making (MCDM) methods and fuzzy logic. The calculation of indicators presents two main difficulties: The nature of the data (numerical, interval, and linguistic values are mixed) and the objective of each criterion (which does not have to reach either the maximum or the minimum). A method is proposed, based on similarity measures with predetermined ideals, that is capable of overcoming these difficulties to provide easy-to-interpret information about the quality of the alternatives. To illustrate the usefulness of this proposed method, it has been applied to data collected from students across nine …
Tres artistas en el exilio: Max Aub, Félix Candela y Josep Renau
2020
Three artists in exile focuses on the historical diaspora provoked by the Spanish civil war (1936- 1939), and how it influenced three prominent figures of the cultural scene of that period: the writer and typographer Max Aub Mohrenwitz (Paris, 1903-Ciudad de Mexico, 1972); the architect Félix Candela Outeriño (Madrid, 1910-Raleigh, US, 1977); and the artist Josep Renau Berenguer (Valencia, 1907-Berlín, 1982). They are the three protagonists of this article, who were simultaneously living in Mexico during the exile and who made notable contributions in the fields of arts and humanities (Max Aub), architecture (Félix Candela), and graphic design and photomontage (Josep Renau). While they were…

The b-chromatic number of power graphs
2003
The b-chromatic number of a graph G is defined as the maximum number k of colors that can be used to color the vertices of G, such that we obtain a proper coloring and each color i, with 1 ≤ i≤ k, has at least one representant x_i adjacent to a vertex of every color j, 1 ≤ j ≠ i ≤ k. In this paper, we discuss the b-chromatic number of some power graphs. We give the exact value of the b-chromatic number of power paths and power complete binary trees, and we bound the b-chromatic number of power cycles.
