Infinite Loop Spaces Associated to Affine Kac-Moody Groups
College of Mathematics and Computer Science, Fujian Normal University, Fuzhou 350108, China
The main purpose of this paper is to construct infinite loop spaces from affine Kac-Moody groups, It is well known that to each infinite class of classical groups over a commutative ring R, we can associate an infinite loop space G(R) by Quillen's plus construction. In this paper we generalize this fact to the cases of affine Kac-Moody groups. Roughly speaking, for each commutative ring R there are seven infinite classes of affine Kac-Moody groups over R, and to each infinite class we can associate an analogous infinite loop space.
Keywords: Infinite loop space, affine Kac-Moody group.
