    "abstract": "The \"snake\" is a persistent density perturbation at the rational q-surfaces\nafter pellet injection. Together with other phenomena (density pinch and\nprofile resiliancy) it can be traced back to the extremum of an action\nfunctional for line-vortices in 3D. In a field theoretical formulation this\nleads to the Liouville equation. We provide explicit method of calculating\nsolutions to the Liouville eq. on periodic domains and obtain, in particular,\nlocalised perturbations similar to the experimentally observed \"snakes\".",
