Preface
This volume contains papers presented at the “Probabilistic Methods in
Fluids Workshop” which was hosted by the Department of Mathematics,
University of Wales Swansea between the 14th and lgth of April 2002.
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

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.

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
