Abstract: (Elsevier)
It is shown that SU(2) Yang-Mills theory can be expressed as an HP 1 = S 4 σ-model, viz., the O(5) generalization of the Skyrme model. Using this equivalence, its reduction to the constrained system on S 4 is constructed and general multi-instanton solutions of the SU(2) Yang-Mills field in curved space with the metric found by Gürsey et al., are obtained.
