Abstract
This paper examines the theory of third sound, without attenuation effects, in layered superfluid films with finite compressibility. This theory, together with the application of a simple thermodynamic model for the film layers shows how the third-sound velocity can undergo strong variations with coverage associated with progressive changes in film compressibility, inlayer phase changes, and layer completion.Keywords
