  The kinetic theory of the Fermi liquid is applied to finite nuclei. The
nuclear collective motion is treated in terms of the observable variables:
particle density, current density, pressure etc. The nuclear dynamics is
influenced strongly by the Fermi-surface distortion (FSD) effect. The
relaxation of collective motion and the width of giant multipole resonances in
hot nuclei show a saturated behaviour with temperature caused by the memory
effect in the collision integral. The development of the bulk and surface
instabilities of the nuclear Fermi-liquid is sensitive to the dynamic effects
such as the FSD and the relaxation processes. The instability growth rate is
reduced due to the FSD effect and depends on the multipolarity of the particle
density and surface fluctuations.
