Mod $p$ decompositions of gauge groups

Full-text: Open access


We give mod p decompositions of homotopy types of the gauge groups of principal bundles over spheres, which are compatible with mod p decompositions of Lie groups given by Mimura, Nishida and Toda. As an application, we also give some computations on the homotopy types of gauge groups. In particular, we show the p –local converse of the result of Sutherland on the classifications of the gauge groups of principal SU ( n ) –bundles.
