Workshop "Conceptual Aspects of Turbulence: Weak vs. Strong"
10-12 October 2007

This workshop brings together a number of researchers working on turbulence in fluids, superfluids, MHD, plasmas (astro, space and laboratory). The goal of the workshop is to discuss what are the physical and mathematical conditions under which turbulent systems that can support linear waves "choose" to be in a weak or strong interaction regime and what can be done to study that in space, in the laboratory, in the computer or on paper.
