Abstract
A phase diagram of pinned soliton structures in two dimensions has been found for a repulsive interaction "U(x) between solitons with U"(x) > 0. The critical fugacity of the commensurate soliton structure is shown to be proportional to U"(l), where l is the period of this structure.
Résumé
Nous avons trouvé un diagramme de phase correspondant à des structures de soliton ancré à deux dimensions dans le cas d'une interaction répulsive U"(x) entre solitons avec U"(x) > 0. Nous montrons que la fugacité critique de la structure de soliton commensurable est proportionnelle à U"(l), où l est la période de cette structure.
