Abstract
Theoretical predictions are given concerning the spectrum of the free surface fluctuation modes in liquid crystals such as smectics and cholesterics. We find drastic differences with simple liquids and nematic liquid crystals. These differences came from two new properties: the elastic energy associated with the layered structure and the permeation, that is the diffusion process of the fluid through the layers.Keywords
