DERIVATIONS AND COMPARISONS OF 3 GROUPS OF SELF-ORGANIZATION THEORIESFOR MAGNETOHYDRODYNAMIC PLASMAS

A theoretical investigation on self-organization theories of dissipati ve MHD plasmas is presented to derive three groups of theories that le ad to the same relaxed state of del x B=lambdaB, in order to find more essential physical picture embedded in self-organization phenomena du e to nonlinear and dissipative processes. Comparisons among all of the theories treated and derived here suggest that a theory standing upon spectrum spreadings and selective dissipations of eigenmodes for the dissipative operator - del x etaj and leading to self-organized relaxe d states of del X etaj = alphaB/2 with the minimum dissipation rate is the most agreeable to various results obtained by experiments and by 3-D MHD simulations reported so far.
