摘要: The problems of existence and stability drift vortices in plasmas with density temperature inhomogeneities are studied analytically numerically. It is shown that basically two space scales involved: (i) the ion Larmor radius at electron temperature, where dipolar exist, (ii) a longer scale on which monopolar possible. latter to survive finite disturbances. A Liapunov functional for structural presented. analytical predictions verified by 2D numerical simulation.
