A sufficient stability condition with respect to purely growing modes is derived for resistive magnetohydrodynamics. Its "nearness" to necessity is analysed. It is found that for physically reasonable approximations the condition is in some sense necessary and sufficient for stability against all mo

β¦ Synopsis
The linear stability properties of the resistive 'g' mode are examined. The effects of including a full stress tensor have been examined for this mode. The nonlinear 'g' mode has also been examined and a potential saturation mechanism identified. The results of 2D calculations for the m = 0 and m = 1 'g' modes in the reverse field pinch (RFP) are presented. Ergodic field line behaviour is found as a result of the interaction of mixed helicity 'g' modes.

## Abstract We report on recent efforts to improve the understanding of the Rosensweig instability in the linear as well as in the nonlinear regime. In the linear regime we focus on the wavenumber of maximal growth and the oscillatory decay of metastable magnetic liquid ridges, accessible via a new
The aim of this paper is to give a simple proof to the fact that linear instability implies nonlinear instability for two classes of boundary layers: Ekman layers, mixed Ekman Hartmann layers. In the case of rotating fluids, we prove that linear instability of Ekman boundary layers (as studied in Li
This paper presents an efficient algorithm for finding all characteristic curves of nonlinear resistive circuits. This algorithm is based on interval analysis and a new computational test for nonexistence of a characteristic curve in a given region X. In this test, the simplex method is applied to a
