A note on the homotopy type of certain gauge groups. (English) Zbl 0722.55008
Summary: Let \(G_ k\) be the gauge group of \(P_ k\), the principal SU(2) bundle over \(S^ 4\) with \(c_ 2(P_ k)=k\). In this paper we show that \(G_ k\simeq G_{k'}\) if and only if \((12,k)=(12,k')\) where (12,k) is te GCD of 12 and k.
