The aim of the meeting, the first IRIMA workshop, was to bring together internationally reknowned researchers from the areas of Pure Mathemat- ics, Applied Mathematics and Engineering to participate in a workshop, on probabilistic methods for fluids, and through collaboration further the mathematical understanding of the fundamental problems in this field. This international workshop successfully allowed leading researchers to present, reflect upon and discuss their recent work in the probabilistic modelling of fluids. This field stretches across Pure Mathematics, Applied Mathematics and Engineering and consequently is ideally placed to benefit from regularly arranged workshops for collaborative purposes. The Work- shop mainly concentrated on the understanding of turbulence in stochastic fluid dynamics, a problem which has numerous applications in science and engineering and has defied many attempts to success full^ model it. The workshop bridged a gap between the recent year of activity at the Univer- sity of Warwick and the year of emphasis at Princeton, which started in Autumn 2002. As such the workshop ensured that the research momentum in Britain, in this subject, was maintained. In this volume probabilistic approaches to hydrodynamic equations are re- viewed and deterministic viscous hydrodynamics is discussed in terms of stochastic processes on groups of diffeomorphisms. At the Workshop sig- nificant progress was made in understanding the intermittence of stochastic turbulence for Burgers equation and the application of L6vy processes to the Mathematics of Finance, both of which are represented in the pro- ceedings. Other noteworthy developments concerned the Strong Law of Large Numbers and ergodicity of the Gaussian invariant measures for 2- dimensional Navier-Stokes equations with space-time white noise and pe- riodic boundary conditions and mean field results for 3-dimensional vortex filaments. Also, new results are presented on Loeb space techniques and attractors for stochastic Navier-Stokes equations. The long time behaviour of stochastic 2-dimensional Navier-Stokes equations is investigated as are vii ... Vll l perturbations by delta correlated noise. Burgers turbulence for white noise initial conditions is discussed in detail and the Cauchy problem for stochas- tic Burgers equation with L6vy space-time white noise is also examined. A complete mathematical analysis of stochastic differential equations arising in micro-macro modelling of polymeric fluids is given. Scientific Organising Committee S. Albeverio, Y.I.

Local Organisation We wish to thank Jane Barham and Janice Lewis for their forebearance before, during and after the workshop in providing secretarial and adminis- trative support. We must thank also Bjorn Boettcher, Victoriya Knopova, Scott Reasons and Chris Reynolds for their contribution towards the suc- cessful running of the workshop. Finally, we thank the referees for their important but anonymous contribu- tion in helping us to finish this volume on time. I M Davies 0 Hassan N Jacob K Morgan A Truman N P Weatherill University of Wales Swansea, December 2002 International Research Institute in Mathematics and its Applications Patron: Sir Michael Atiyah OM, FRS There is no such thing as Applied Science only the Applications of Science, Henri Poincark We have established the International Research Institute in Mathematics and Its Applications, IRIMA, (Sefydliad Ymchwil Rhyngwladol i Fathe- mateg a’i Chymwysiadau, SYRIFAC) with the aim of conducting a series of research programmes in Mathematics and its applications to Engineer- ing and Science. In so doing we aim to accelerate the transfer of modern Mathematics to Engineering and the Sciences. These programmes should be seen to be interdisciplinary, with the express intention of providing a forum for interaction between groups of mathematicians, engineers and sci- entists, while at the same time preserving the integrity of the Mathematics being utilised. The Institute will be based in Swansea and will draw on existing strengths in Stochastic Processes, Physical Mathematics, Finite Element Methods and Theoretical Computer Science. Swansea (in the person of Oleg Zienkiewicz FRS) pioneered the use of Finite Element Methods in Engineering. More recently, his research group, which includes Profs. Nigel Weatherill, Ken Morgan FREng and Roger Owen FREng, has done vitally important re- search work in a number of different application areas, including work on the European Airbus and Thrust SSC, the supersonic car. Swansea also has international centres of research excellence in Probability Theory and ix
