A semiclassical linear response theory based on the Vlasov equation is reviewed. The approach discussed here differs from the classical one of Vlasov and Landau for the fact that the finite size of the system is explicitly taken into account. The non-trivial problem of deciding which boundary conditions are more appropriate for the fluctuations of the phase-space density has been circumvented by studying solutions corresponding to different boundary conditions (fixed and moving surface). The fixed-surface theory has been applied to systems having both spherical and spheroidal equilibrium shapes. The moving-surface theory is related to the liquid-drop model of the nucleus and from it one can obtain a kinetic-theory description of surface and compression modes in nuclei. Quantum corrections to the semiclassical theory are also briefly discussed.
