The gauge group of $P$ is the topological group of automorphisms of $P$. For fixed $G$ and $K$, consider all principal $G$-bundles $P$ over $K$. It is proved by Crabb--Sutherland and the second author that the number of $A_n$-types of the gauge groups of $P$ is finite if $n<\\infty$ and $K$ is a finite complex. We show that the number of $A_\\infty$-types of the gauge groups of $P$ is infinite if $K$ is a sphere and there are infinitely many $P$.", "revisions": [ { "version": "v1", "updated": "2015-02-10T05:14:58.000Z" } ], "analyses": { "subjects": [ "57S05", "55P48" ], "keywords": [ "gauge group", "infiniteness", "compact connected lie group", "second author", "finite complex" ], "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150202781K" } } }
