Mercier criterion explained

The Mercier criterion is a criterion for plasma used in the theoretical study of plasma instability. It was first proposed in 1954 by C. Mercier, who applied the perturbation method (in which

\omega = (\partial)/(\partial t) represents the frequencyand k = (\partial)/(\partial z) is the z-direction of the unit vector) to the plasma mathematical model to compute calculations.^{[1] [2]}
