Odd primary homotopy decompositions of gauge groups. (English) Zbl 1196.55009
Given a principal $$G$$-bundle $$P \to X$$, the gauge group $$G(P)$$ is the group of equivariant automorphisms of $$P$$ over $$X$$. The problem of determining the homotopy types of gauge groups has been of interest for some time. The rational homotopy type was found in [Y. Félix and J. Oprea, Proc. Am. Math. Soc. 137, No. 4, 1519–1527 (2009; Zbl 1168.55010)]. Here, for certain specific bundles, the author generalizes the rational decomposition to a $$p$$-local decomposition. In particular, the author achieves this for $$SU(n)$$, $$Sp(n)$$ and $$Spin(n)$$-bundles over simply connected $$4$$-manifolds and for $$U(n)$$-bundles over compact orientable Riemann surfaces when the prime $$p$$ is restricted in specified ways. A main tool for all results is the spatial decomposition of a ($$p$$-localized) group $$G$$ corresponding to the well-known algebra decomposition $$H_*(G) \cong \otimes_{i=1}^{p-1} \Lambda(V_i)$$, where $$V_i$$ consists of generators constrained by degree in terms of $$p$$.
