摘要

Let S be a finite union of (pairwise disjoint but possibly knotted and linked) closed curves and tubes in the round sphere S-3 or in the flat torus T-3. In the case of the torus, S is further assumed to be contained in a contractible subset of T-3. In this paper we show that for any sufficiently large odd integer lambda there exists a Beltrami field on S-3 or T-3 satisfying curl u = lambda u and with a collection of vortex lines and vortex tubes given by S, up to an ambient diffeomorphism.
