Analysis of nonlinear dynamical systems for the description of plasma stochastization (Q1336300)

The analysis of dynamics system of the magnetic field perturbation amplitude is done in order to understand the nonlinear effects responsible for the stochasticity of the system. Starting from the MHD equations, approximate solutions for the magnetic field and the plasma velocity potentials were expressed in terms of series expansions. The resulting nonlinear coupled equations were then numerically investigated, with a particular attention focussed on the equilibria and the related stability conditions, and on their dependence on the corresponding coupling coefficients.
