We have derived a dispersion differential equation suitable for studying free and forced oscillations of a radially inhomogeneous plasma cylinder in the ion cyclotron range of frequencies (ICRF). Solving the differential equation, subject to appropriate boundary conditions, yields global eigenmodes of the cylindrical configuration; thus, our description embraces both the geometry and the physics relevant in the ICRF. The derivation begins with the equations of the Vlasov(ion)-fluid(electron) model. An approximate solution of the ion Vlasov equation is obtained analytically for a general screw pinch equilibrium by restricting the ion gyroradius to small, but finite values.
