[For the construction of merons and related flat space solutions via De Sitter space, see the section 4 of H. Boutaleb-Joutei, A. Chakrabarti, and A. Comtet, Phys. Rev., t. D 20, 1979, p. 1884. Here the aim is to introduce from the beginning, along with spherical symmetry, the consequences of the meron ansatz (Aμ = i/2(∂μU)U-1) and explore the special features thus introduced. The spherically symmetric ansatz has been studied by several authors. See, for example. A.N. Leznov and M.V. Saveliev, Phys. Lett., t. 79 B, 1978, p. 294, and the review article by F.A. Bais, « O(3) symmetric monopoles and instantons » (talk presented at International Workshop, Serpukhov, July, 1979). Joint rotations (isospin and space) were systematically exploited for SU(3) by A. Chakrabarti, Ann. Inst. H. Poincaré, t. 23, 1975, p. 235. The same ansatz for SU(3) was also adopted in E. Corrigan, D.I. Olive, D.B. Fairlie and J. Nuyts, Nucl. Phys. t. B 106, 1976, p. 475.
