Nonlinear Pulmonary and Cardiovascular Fluid Flows (3rd June 1998)

University of Surrey

A half-day workshop on Nonlinear Pulmonary and Cardiovascular Fluid Flows will be held at the University of Surrey on Wednesday 3rd June, organised by David Gammack. It is supported by a grant from the London Mathematical Society.

The workshop will have a talk by a leading expert, Professor T. Pedley FRS (Cambridge), and the remainder of the talks will be given by Postdoctoral Fellows and Postgraduate Students. Scheduled talks include Andrew Hazel (Cambridge), Matthias Heil (Cambridge) and Susan Todd (Surrey). All interested participants are welcome and some funds are available to help with travel costs. Further information can be obtained by contacting the organiser at and updated information, including abstracts of talks and directions to the university, will be posted on the web at

Workshop on Skew Product Systems (5 June 1998)

Queen Mary and Westfield College, University of London

This one-day workshop at the School of Mathematical Sciences, QMW, London, will look at aspects of the theory and application of dynamics of skew product systems. The main topics of the workshop include random dynamical systems, systems under the influence of chaotic, quasiperiodic or periodic forces, coupled systems, group extensions of dynamical systems, central limit theorems, ergodicity, mixing, decay of correlations, statistical mechanics and thermodynamic formalism.

Speakers will include:

W. Parry Warwick
L. Arnold Bremen
P. Glendinning QMW

In addition, there will be short talks and discussion groups by participants. Talks will start at 11am in the Mathematics Building, room M103. The nearest underground station is Stepney Green.

This meeting is supported by a scheme 3 grant of the London Mathematical Society (Joint Research Group in the dynamics of skew product systems) and by the Mathematics Research Centre at QMW. Limited funds for travel within the UK are available.

If you would like to participate, send an e-mail to or write to Dr. C. Beck, School of Mathematical Sciences, Queen Mary and Westfield College, Mile End Road, London E1 4NS, UK. In case you would like to contribute a short talk, please provide a title and an abstract.

Workshop on Periodic Orbits in Biology (11-12 July 1998)

Fairfax, VA, USA

I have received funding from the Theoretical Division of the National Institutes of Health to sponsor a short two day workshop on Periodic Orbit Theory in Biology.

My desire is to take the evolving applications of this physics theory to biological experiments, and present it to a small group of theorists and experimentalists (less than 40) who would have significant insight into both the potential implications and limitations of this approach. My desire is to have eight speakers per day over two days, with substantial time for discussion. There will be a poster session as well, and I invite everyone attending who is not speaking to present aspects of their dynamical work in this format - I will make sure that the poster session is a serious one. I hope that in the wake of such a meeting, that new experimental and theoretical work would be initiated, as well as new collaborations.

Confirmed speakers and participants thus far include: Celso Grebogi, Ed Ott, Frank Moss, Jim Collins, Mark Spano, Paso So, Tim Sauer, Lou Pecora, Tom Carrol, Ying-Cheng Lai, Peter Schmelcher, Henri Korn, Eric Kostelich, Juergen Kurths, Michel Le Van Quyen, and Predrag Cvitanovic.

This meeting would be held at the Krasnow Institute for Advanced Studies at the George Mason University, Fairfax, VA, close to the Washington DC airports and the University of Maryland.

I am hoping to produce a well focused workshop on what is (should be) one of the more exciting aspects of overlap between theoretical physics and dynamical biology.

Integrability: the Seiberg-Witten and Whitham Equations (14-19 September 1999)


The International Centre for Mathematical Sciences will be running a five-day workshop in Edinburgh, September 14th-19th, 1998. The intention is to bring together mathematicians and mathematical physicists with interests in integrability and its applications. The general objectives are:

  1. To discuss the general algebro-geometric and geometric structures underlying integrability and specifically to clarify the appearance of integrable structures in Seiberg-Witten theory.
  2. To discuss the Whitham equations and their application in the generalised WKB analysis of (integrable) systems, particularly their appearance in connection with Seiberg-Witten theory.
  3. To discuss systems of hydrodynamic type, Frobenius manifolds and algebras.
  4. To develop interdisciplinary links and establish new connections between different areas that employ facets of integrability.
  5. To enhance collaborative research by bringing together participants from different areas of pure mathematics, applied mathematics and theoretical physics.

Organisers: H.W. Braden, D.B. Fairlie, I. Krichever, I.A.B. Strachan, G. Wilson.

Stochastic and Chaotic Dynamics in the Lakes (16-20 August 1999)


Preliminary Announcement

The aim of the conference is to provide a forum for the discussion of developments in nonlinear science, making special efforts to promote connections between the deterministic and stochastic communities. The meeting will review both theory and its applications and bring together experts from the international community.

The last few years have brought an enormous increase in the number of scientists working on nonlinear problems and many important new phenomena have been discovered. The time is ripe to bring together experts from the hitherto largely distinct traditions of deterministic dynamical systems and stochastic nonlinear processes. Practical applications of fundamental results in these areas are beginning to appear across the entire spectrum of science. The interdisciplinary nature of this work means that while communication between researchers is vital it is difficult to achieve because of the range of scientific cultures involved. A central aim of the conference therefore, will be to build bridges between the communities by promoting themes of common interest.

The conference will draw on international invited speakers selected for their ability to span gaps, address a wide audience, see connections, and help to integrate related results coming from far-flung parts of the subject area. It will take place in Ambleside, in the heart of the English Lake District. There are few competing attractions apart from the outstanding natural beauty of the mountains and lakes, and it is expected that some of the most useful scientific interactions will take place after or between the stimuli provided by the formal sessions, while participants are walking on the hills or enjoying Lake Windemere.
