| Given a reductive group G over a local non-archimedean field F, Bruhat and Tits defined its building B as a certain (infinite) simplicial complex that carries a lot of information about the structure of G (e.g., it can be used to parametrize norms on G or filtrations of G(O_F) by compact subgroups).
The goal of the thesis is to study buildings B of specific groups G, to explicitly describe B and the corresponding filtrations, and to determine geometrical and combinatorial properties of B (e.g., by giving formulas for the number of points in balls). Already the case when G is split classical is very non-trivial, but it would be even more interesting to compare this with the non-split situation. Time permitting, the student may then focus on some of the applications of buildings, for example to representation theory. Among other things, the thesis will require learning the basics of linear algebraic groups and p-adic fields. |
