Abstract
The frequency spectrum of tearing modes is analyzed with the help of a mode coupling model including toroidal effects in the MHD regions and various non-linear effects in the resonant layers. In particular, it is shown that the sudden damping of the mode rotation and the simultaneous enhancement of the growth rate observed in Tokamaks could be explained as a bifurcating solution of the dispersion equation.Keywords
