Journal of Lie Theory 23 (2013), No. 3, 699--709 Copyright Heldermann Verlag 2013 Infinite Loop Spaces Associated to Affine Kac-Moody Groups Xianzu Lin College of Mathematics and Computer Science, Fujian Normal University, Fuzhou 350108, China linxianzu@126.com 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. MSC: 55P47, 20G44 [ Fulltext-pdf (329 KB)] for subscribers only. |
