This paper deals with the theoretical investigation of low-frequency drift and trapped-particle instabilities in systems with magnetic shear, by analytic and numerical procedures and by computer simulations. In particular, results are presented for calculations which demonstrate: (1) the stability of both collisionless and dissipative drift eigenmodes at long radial wavelengths (k/sub r/rho/sub i/ less than 1) in a sheared slab (one-dimensional) geometry; (2) the presence and structure of drift and trapped-electron eigenmodes in an axisymmetric toroidal (two-dimensional) geometry; and (3) the nonlinear evolution and resultant anomalous transport from trapped-electron instabilities.
