Plusieurs algorithmes ont été proposés pour la construction de hiérarchies de classes à partir de la spécification de leurs propriétés. Entre autres, les algorithmes proposés dans (Dicky, Dony, Huchard & Libourel, 1994) et (Godin, Mineau & Missaoui, 1995a) préservent la structure de sous-hiérarchie de Galois de la relation entre les classes et leurs propriétés. De plus ces algorithmes peuvent i...

Let M be a closed, oriented, n-dimensional manifold. In this paper we give a Morse theoretic description of the string topology operations introduced by Chas and Sullivan, and extended by the first author, Jones, Godin, and others. We do this by studying maps from surfaces with cylindrical ends to M , such that on the cylinders, they satisfy the gradient flow equation of a Morse function on the...
