What is it about?
The solid-like behavior of many liquids at low frequencies has been experimentally demonstrated by many authors. In this paper, we will develop a groundbreaking theoretical model having no equivalent to our knowledge, such that it will lead us to admit that any finite volume of a liquid at rest must be considered as a solid with low but finite static shear elasticity.

Why is it important?
In particular, this development will allow us to justify the phenomenological relations introduced in Ref. 11 to describe transport coefficients. The whole analysis has shown that the shear moduli G, G’ and G’’ are scaled by the shear elastic constant K, but are not constants of the medium in the sense that their values depend on the experimental conditions.
Perspectives
This new approach opens perspectives to explore and offer a better understanding of different problems such as Rayleigh-Bénard type flow instabilities, wetting phenomena or microfluidic flow.
