We form.late the general relativistic m.gnetohydrodynam.c equations for isotherm.l plasm. in spatially fiat Reissner-Nordstroem.de Sitter m.tric by using 3＋1 split of spacetim.. Respective perturbed equations are linearized for rotating m.gnetized surroundings. These are then Fourier analyzed and the corresponding dispersion relations are obtained. These relations are discussed both analytically and num.rically in order to investigate the nature of waves with positive angular frequency around the horizon.
