DESCRIPTION:We construct simply laced semisimple Lie algebras L with struc
ture constants built into the Lie bracket. This also gives structure const
ants for the simply connected Chevalley group associated to the Lie algebr
a L. For infinite dimensional simply laced Kac-Moody algebras and their as
sociated Kac-Moody groups\, we obtain a complete description of the struct
ure constants for root vectors corresponding to real roots whose sum is re
al. This is joint work with Pierre Cartier.\n\nhttps://indico.math.cnrs.fr
