Soit un corps fini de caractéristique et soit un corps -adique où . Étant donnée une représentation , où est une -algèbre locale, nous étudions le problème de la recherche de -module admissible qui « interpole la correspondance de Langlands locale » pour sur les points de . Nous formulons une version précise de ce problème et montrons qu'il a au plus une solution, à isomorphisme près. Le premier auteur a montré [6] que lorsque est une algèbre de Hecke, et est la représentation naturelle de sur , alors le -module existe et apparaît naturellement dans la cohomologie de la tour des courbes modulaires.
Let be a finite field of characteristic , and let be an -adic field for . Given a representation where is a local -algebra, we study the problem of finding an admissible -module that “interpolates the local Langlands correspondence” for over the points of . We formulate a precise version of this problem and show that it has at most one solution, up to isomorphism. The first author has shown [6] that when is a Hecke algebra, and is the natural representation of over , the corresponding -module exists and arises naturally in the completed cohomology of the tower of modular curves.
