Spherically symmetric Dirac-Yang-Mills pairs on Riemannian 3-manifolds

In this paper we construct examples of spherically symmetric Dirac-Yang-Mills pairs on Riemannian 3-manifolds with the structure group SU(2). This approach yields coupled solutions (i.e. the connection is not a Yang-Mills connection) and among them are solutions on S^1(r_1) x S^2(r_2) for certain radii r_1 and r_2. These are, to the authors’ best knowledge, the first examples of coupled Dirac-Yang-Mills pairs on a closed Riemannian spin manifold.
