We obtain sufficient conditions for the existence of the Ambjorn-Olesen [“On electroweak magnetism,” Nucl. Phys. B315, 606–614 (1989)10.1016/0550-3213(89)90004-7] electroweak N-vortices in case N ⩾ 1 and therefore generalize earlier results [D. Bartolucci and G. Tarantello, “Liouville type equations with singular data and their applications to periodic multivortices for the electroweak theory,” Commun. Math. Phys. 229, 3–47 (2002)10.1007/s002200200664; J. Spruck and Y. Yang, “On multivortices in the electroweak theory I: Existence of periodic solutions,” Commun. Math. Phys. 144, 1–16 (1992)10.1007/BF02099188] which handled the cases N ∈ {1, 2, 3, 4}. The variational argument provided here has its own independent interest as it generalizes the one adopted by Ding et al. [“Existence results for mean field equations,” Ann. Inst. Henri Poincare, Anal. Non Lineaire 16, 653–666 (1999)10.1016/S0294-1449(99)80031-6] to obtain solutions for Liouville-type equations on closed 2-manifolds. In fact, we obtain at once...
