| Abstract: | We investigate some aspects of Bogomolny-Prasad-Sommerfield monopole solutions in the Yang-Mills-Higgs theory with the exceptional gauge group G2 spontaneously broken to U(1)×U(1). The corresponding homotopy group is π2(G2/U(1)×U(1)), and similarly to the SU(3) theory, the G2 monopoles are classified by two topological charges (n1,n2). In the fundamental representation, these yield a subset of SO(7) monopole configurations. Through inspection of the structure of Alg(G2), we propose an extension of the Nahm construction to the (n,1)G2 monopoles. For the (1,1)G2 monopole, the Nahm data are written explicitly. |
