special combinatorics seminar

gent university, belgium

two lectures on $\mathbb f_1$ -- i. the weyl functor

abstract:

starting from the notion of bn-pair (which is closely related to the concept of tits building), we explain, following a classical insight, how one interprets buildings and their automorphism groups over the nonexisting ``field with one element". (as such, the symmetric groups become chevalley groups over this ``field".) we then introduce scheme theories in ``characteristic one", and show how these are governed by a deep combinatorial (and motivic) nature.
