1. M. N. Rosenbluth and C. Longmire, Ann. Phys., 1:120 (1957). It is suggested that the physical effects of gravitational and magnetic drift are idential (§11.1). The stability condition (11.21) is obtained. It is shown that a plasma in an axisymmetric field configuration is unstable (§11.3).
2. B. R. Suydam, in: Hot Plasma Physics and Thermonuclear Reactions [Russian Collection of Translations], Atomizdat (1959), p. 89. It is shown that a shear has a stabilizing effect in a plasma with cylindrical symmetry (§11.6).
3. J. L. Johnson et al., Phys. Fluids, 1:281 (1958). Study of the effect of stabilization by a shear produced by external conductors (§11.7). Energy considerations yield the stability condition V″ < 0 (§11.8).
4. B. B. Kadomtsev, in: Plasma Physics and the Problem of Controlled Thermonuclear Reactions, Vol. 4, Pergamon Press, Oxford (1960), p. 17. Contains a proof of the equation [∇ρ, ∇U] = 0. Curvilinear coordinates are used. The stability condition (11.21) is obtained.
5. I. B. Bernstein et al., Proc. Roy. Soc, A244:17 (1958). It is shown that balloontype perturbations can develop (§11.5). The condition (11.44) is derived.
