Abstract:
In this talk, we provide a realization of twisted affine Kac-Moody groups as twisted loop groups by means of Galois descent considerations. We also give a natural description of the twisted/untwisted affine Kac-Moody groups and Lie algebras using the language of reductive group schemes of Demazure-Grothendieck. Joint work with J. Morita and A. Pianzola.
