Faraday waves are gravity-capillary waves that form on the surface of a liquid when the container vibrates. These waves can organize themselves into a great variety of patterns with different spatio-temporal symmetries. The problem is particularly interesting in the nearly inviscid regime where the Faraday waves couple to a streaming flow driven in oscillatory viscous boundary layers; this flow in turn interacts with the waves responsible for the boundary layers, leading to a description of the system in terms of amplitude equations coupled to a Navier-Stokes-like equation for the streaming flow. Depending on the container shape these equations exhibit rich dynamics close to the onset of the Faraday instability. http://www.maths.usyd.edu.au/u/AppliedSeminar/abstracts/2008/knobloch.html
