Edifices: building-like spaces associated to linear algebraic groups
Given a semisimple linear algebraic k-group G, one has a spherical building ∆ G , and one can interpret the geometric realisation ∆ G (R) of ∆ G in terms of cocharacters of G.The aim of this paper is to extend this construction to the case when G is an …
