In a previous paper, we gave a correspondence between certain exact solutions to a (2 + 1)-dimensional integrable Chiral Model and holomorphic bundles on a compact surface. In this paper, we use algebraic geometry to derive a closed-form expression for those solutions and show by way of examples how the algebraic data which parametrise the solution space dictates the behaviour of the solutions.

Résumé

Résumé

Dans un article précédent, nous avons démontré que les solutions d’un modèle chiral intégrable en dimension (2 + 1) correspondent aux fibrés vectoriels holomorphes sur une surface compacte. Ici, nous employons la géométrie algébrique dans une construction explicite des solutions. Nous donnons une formule matricielle et illustrons avec trois exemples la signification des invariants algébriques pour le comportement physique des solutions.
