Abstract

We announce a theorum which states that, over certain fields, affine Kac-Moody groups of types II and III arise as the fixed point subgroups under particular automorphism of affine Kac_moody groups obtained from a simply laced extended Cartan matrices (and hence of type I) of higher rank. Thus our result extends a theorum on Kac-Moody algebras to corresponding groups. A detailed proof of this result will appear in the J. Algebra.
