A topological monopolelike field configuration exists for Yang-Mills gauge fields in 4+1 dimensions. When the extra dimension is compactified to 3+1 dimensions with periodic lattice boundary conditions, these objects reappear in the low-energy effective theory as a novel solution, a gauged-bosonic Skyrmion. When the low-energy theory spontaneously breaks, the Nambu-Goldstone mode develops a vacuum expectation value, and the gauged-bosonic Skyrmion morphs into a 't Hooft–Polyakov monopole.
