Magnetohydrodynamic waves in a sheared potential coronal arcade
We study the effects of magnetic field shear (By ≠ 0) and longitudinal propagation of perturbations (ky ≠ 0) on the linear and adiabatic magnetohydrodynamic (MHD) normal modes of oscillation of a potential coronal arcade. In a cold plasma, the inclusion of these two effects produces the linear coupling of discrete fast modes, characterised by a
