Chromatic Factorisations
The chromatic polynomial gives the number of proper λ-colourings of a graph G. This paper considers factorisation of the chromatic polynomial as a first step in an algebraic study of the roots of this polynomial. The chromatic polynomial of a graph is said to have a chromatic factorisation if P (G, λ) = P (H1, λ)P (H2, λ)/P (Kr, λ) for some graphs H1 and H2 and clique Kr. It is known that the c...
متن کاملRelations explicites entre différentes représentations d'image dans un modèle de graphe visuel
This paper presents a novel approach, the first to our knowledge, that exploits a complete extension of the language modeling approach from information retrieval to the problem of graph-based image retrieval and categorization. Since photographic images are 2D data, we first use image regions and local interest points (mapped to automatically induced concepts) and then relationships between the...
متن کاملLa reformulation hybride des requêtes exploratoires à l'aide de concepts explicites et implicites
Explorative web queries are often short and ambiguous. In addition, using named entities in this type of queries is well-known and frequent. In this paper, we explore query reformulation for adding terms belonging to query concepts. We distinguish two types of concepts: explicits ones that correspond to named entities having references to concepts in the Yago ontology, and implicit ones that we...
متن کاملDeformation of Algebra Factorisations
A deformation theory of algebras which factorise into two subalgebras is studied. It is shown that the classification of deformations is related to the cohomology of a certain double complex reminiscent of the Gerstenhaber-Schack complex of a bialgebra.
متن کاملUne approche de la stabilisation interne par l’analyse algébrique I. Factorisations doublement faiblement copremières
Résumé—Ce papier a pour but de donner une vue générale des différents résultats récemment obtenus sur la stabilisation interne des systèmes linéaires de dimension infinie. On s’attachera à faire ressortir les principales idées plus que la technique utilisée. En particulier, nous donnerons des conditions nécessaires et suffissantes à la stabilisation interne et à l’existence de factorisations do...
