MHD Stability and Constraints

POSTER

Abstract

Following up on previous work [1-3] we present examples of MHD equilibria for which we compare/contrast Lagrangian, Eulerian, and Dynamically Accessible stability. These kinds of stability differ by the constraints employed. Such constraints will be discussed, along with explicit examples including simple convective instability and cylindrical configurations with plasma flow.\\[4pt] [1] T. Andreussi, P.J.
