Abstract.
Non-linear force-free fields (or Beltrami fields) are three-component divergence-free fields solutions of the equation curl B x B = 0. The aim of this paper is to prove existence of solutions of a corresponding boundary value problem in a simply or multiply connected domain of \({\Bbb R}^3\). The proof is based on a fixed point procedure coupled with a singular perturbation skill.
