    "abstract": "It is demonstrated that the deformation of magnetic field lines in\nincompressible magnetohydrodynamic flows results from a compressible mapping.\nAppearance of zeroes for the mapping Jacobian correspond to the breaking of\nmagnetic field lines, associated with local blowup of the magnetic field. The\npossibility of such events is found to be unlikely in two dimensions but not in\nthree dimensions.",
