ABSTRACT
This chapter describes the averaged ballooning equation in the inertial-resistive layer modified by the drift and viscosity effects. It examines an approximate analytical solution of the averaged ballooning equation in the inertial-resistive layer allowing for the electron viscosity in addition to the ion viscosity. The chapter considers the drift-reconnecting and drift-tearing instabilities due to the electron viscosity and the ion viscosity. A solution is expressed in terms of confluent hyper-geometrical functions. The dispersion relation allows one to elucidate the question of the instability considered for a high plasma pressure. The chapter shows that the growth rates of the viscous resistive-interchange instability and viscous-resistive kink modes decrease with increasing drift effects, while in the case of the viscous-resistive ballooning instability, drift effects lead only to the appearance of the real part of the oscillation frequency.
