T H E HELICITY OF A KNOTTED VORTEX FILAMENT
R.L. RICCA' and H.K.MOFFATT' Institute for Theoretical Physics University of California Santa Barbara, California 93106-4030 U.S.A. ABSTRACT. The helicity 31 associated with a knotted vortex filament is considered. The filament is first constructed starting from a circular tube, in three stages involving injection of (integer) twist, deformation and switching of crossings. This produces a vortex tube in the form of an arbitrary knot K; each vortex line in the tube is a (trivial) satellite of I
