Non-archimedean intersection indices on projective spaces and the Bruhat-Tits building for PGL
[Indices d’intersection non archimédiens sur les espaces projectifs et l’immeuble de Bruhat-Tits de PGL]
Annales de l'Institut Fourier, Tome 51 (2001) no. 6, pp. 1483-1505.

Nous interprétons les nombres d’intersection non archimédiens des cycles linéaires sur ℙ n-1 avec la géométrie combinatoire de l’immeuble de Bruhat-Tits associé à PGL(n). Ces résultats sont inspirés par le travail de Manin donnant une interprétation géométrique de la théorie d’Arakelov aux places infinies pour les courbes.

Inspired by Manin’s approach towards a geometric interpretation of Arakelov theory at infinity, we interpret in this paper non-Archimedean local intersection numbers of linear cycles in ℙ n-1 with the combinatorial geometry of the Bruhat-Tits building associated to PGL(n).
