Abstract:
International audience We develop a method for counting words subject to various restrictions by finding a combinatorial interpretation for a product of formal sums of Laguerre polynomials. We use this method to find the generating function for $k$-ary words avoiding any vincular pattern that has only ones. We also give generating functions for $k$-ary words cyclically avoiding vincular patterns with only ones whose runs of ones between dashes are all of equal length, as well as the analogous results for compositions. Nous développons une méthode pour compter des mots satisfaisants certaines r

Abstract:
International audience We give two combinatorial interpretations of the Matrix Ansatz of the PASEP in terms of lattice paths and rook placements. This gives two (mostly) combinatorial proofs of a new enumeration formula for the partition function of the PASEP. Besides other interpretations, this formula gives the generating function for permutations of a given size with respect to the number of ascents and occurrences of the pattern $13-2$, the generating function according to weak exceedances and crossings, and the $n^{\mathrm{th}}$ moment of certain $q$-Laguerre polynomials.

Abstract:
Le caractere semi-classique ou laguerre-hahn d'une forme lineaire reguliere reste stable par la multiplication par un polynome ou par adjonction d'une masse de dirac. La suite associee d'une suite de polynomes semi-classiques est de laguerre-hahn. Ces diverses operations permettent de generer d'autres suites orthogonales dont on etudie les proprietes. On donne aussi diverses caracterisations des polynomes de laguerre-hahn

On étudie les polynômes corécursifs et les polynômes associés des polynômes de Laguerre Hahn affines. On généralise tous ces résultats aux polynômes semiclassiques discrets (avec l'opérateur de Hahn)

Abstract:
Markov-type inequalities provide upper bounds on the norm of the (higher order) derivative of an algebraic polynomial in terms of the norm of the polynomial itself. The present thesis considers the cases in which the norms are of the Laguerre, Gegenbauer, or Hermite type, with respective weights chosen differently on both sides of the inequality. An answer is given to the question on the best constant so that such an inequality is valid for every polynomial of degree at most n. The demanded best constant turns out to be the operator norm of the differential operator. The latter conicides with

Nous presentons d'abord deux methodes pour la planification de trajectoires en presence des obstacles de formes polygonales dans l'espace 2-d. La premiere est basee sur les graphes de visibilite. La seconde utilise les points de demarcation pour reduire la complexite de calcul. Pour resoudre effectivement le probleme en presence des obstacles de formes arbitraires, nous proposons la troisieme methode qui consiste en un reseau neuronal pour transformer l'espace libre en trajectoi
