Retrieving Library Functions by Unifying Types Modulo Linear Isomorphism

Cet article presente une nouvelle methode pour la recherche d'une fonction dans une bibliotheque de programmes a partir de son type (au sens de Hindley/Milner). Les methodes utilisees jusqu'ici identifient les types qui sont isomorphiques dans n'importe quelle categorie cartesienne fermee (CCF), et le type resultat est soit isomorphe au type demande, soit en est une generalisation. Il est quelquefois utile d'instancier le type demande, ce qui necessite de resoudre un probleme d'unification modulo isomorphismes. Bien que l'unification modulo CCF-isomorphismes soit indecidable, ce probleme est decidable modulo isomorphismes lineaires, c'est-a-dire isomorphismes dans une categorie monoidale fermee symetrique
