Bifurcation from a stationary solution to a 2D Torus for tearing unstable plasmas Original Research Article

We give a mathematical justification, using results of [1,2], of a bifurcation from a stationary solution to a quasiperiodic solution evolving on a 2D torus, for the problem of the double tearing instability of a plasma described by MHD equations. A numerical example of such a transition is then given.
