Wonderful compactifications of Bruhat-Tits buildings

The main question of this paper is to understand, when k is a non-archimedean local field, the relationship between the (so-called wonderful) projective variety compactifying

The presentations covered topics such as pattern recognition, models for spatio-temporal data, mobile data management in health applications, and videogames to evaluate

In addition to each node’s links to its predecessor and first r successors, we have three additional types of links: leaf-parent links between bottom and upper level nodes;

Group action on the compactifications In this section, for a given reductive group G over a complete non-Archimedean field k and a given k-rational type t of parabolic subgroups of

As to the topological type, we recall that the fundamental group of C l is of or- der 2, and since we are using an even number of modifications and starting from the trivial bundle,

(1) In the proof above, the assumption that X 0 is a building was only used to pull back the CAT(0) metric, and therefore the result generalizes to more general extensions into

In order to describe some subgroups in terms of the action on the Bruhat-Tits building, in Section 3.1, we recall how the simplicial structure of the building is defined thanks to

Here, we are interested in the simplest approach: in the real case, it consists in seeing each point of a symmetric space as a maximal compact subgroup of the isometry group (via
