Nonlinear Mechanics

6 November 2000, Centre for Nonlinear Mechanics, University of Bath

There will be a meeting on the theme of Nonlinear mechanics on the 6th. November, at the Conference Centre, 8W, {\bf University of Bath} hosted by the Bath Centre for nonlinear mechanics. This meeting will be a mixture of presentations and informal discussion with the aim of generating discussion between different disciplines. The meeting aims to identify clear links between applied mathematics, engineering and industry, based around a common theme of nonlinear problems. It will provide a showcase of successful applications of ideas in nonlinear systems to a wide variety of engineering problems showing clearly the importance of the underpinning of the mathematical ideas.

Topological methods in the physical sciences

15-16 November 2000, Royal Society of London

A Royal Society discussion meeting is being held on Wednesday 15 and Thursday 16 November 2000 at the Royal Society in London, on Topological methods in the physical sciences. It is being organised by Dr H.K. Moffatt FRS, Dr V.I. Arnold, Professor J.W. Bruce and Dr R.B. Pelz.

This meeting will focus on four areas of mathematical physics in which topological ideas and methods find natural application: caustics in optics and quantum physics; fluid mechanisms and magnetohydrodynamics; quantum field theory models; and the large-scale structure of the Universe.

Evolutionary Epidemiology of Strain Structure in Pathogen Populations

15-16th January 2001, Warwick

Organising committee:
Graham Medley Biological Sciences, Warwick
Gabriela Gomes Biological Sciences, Warwick
Sunetra Gupta Zoology, Oxford
Simon Levin Ecology and Evolutionary Biology, Princeton
Robert Mackay Mathematics, Warwick
James Nokes Biological Sciences, Warwick

The aim of the meeting is to provide an environment for theoretically-orientated researchers and data-orientated researchers to discuss the important issues concerning the transmission dynamics of multistrain pathogens. We perceive the identification of appropriate model structures to be the crucial next step, although others will have different priorities.

At this stage we are seeking expressions of interest, and giving advanced warning. If you are interested in participating please contact M.G.M.Gomes@warwick.ac.uk. Further details will be discussed with potential participants.

Modelling Cell Systems: The Post Genomic Challenge

15 - 16 February 2001, UCL, London

A UK CytoCom Workshop to survey the growing range of mathematical and computational techniques used in the modelling of cell systems

Programme organiser: Stephen Baigent, CoMPLEX, UCL.

The great advances in molecular biology of recent decades have uncovered some of the details of cellular make-up. Today rapid advances in microarray and other bioinformatical technologies are providing us with detailed experimental data in vast quantities, and of a novel kind. As a result, we are now forced to rethink the way we build, validate and interpret models of cells and cellular systems. The aim of this two-day workshop is to provide a brief survey of existing and emerging mathematical and computational methods that could help to move the modelling of cellular systems into the data rich 21st century.

Topics we hope to cover:

Stochastic and deterministic approaches, dynamical systems theory, bifurcation analysis, network theory, biochemical reaction theory, boolean networks, category theory, gene networks, protein-protein interactions, cell-cell interactions, cytokine networks, signalling cascades, cellular automata, multiple time scale analysis, time series analysis, systems theory, continuous systems modelling, bond graphs, network thermodynamics, neural networks, biological information transfer.

Speakers include:

Michael Mackey McGill University
Dennis Bray Cambridge University
Robin Callard CoMPLEX, UCL
David Broomhead UMIST
David Fell Oxford Brookes University
Cliburn Chan CoMPLEX, UCL.
Mark Poolman Oxford Brookes University
Olaf Wolkenhauer UMIST
Tim Porter Bangor University
Ray Paton Liverpool University
Hamid Bolouri Herts. University
Henggui Zhang Leeds University
Silvia Nagl CoMPLEX, UCL
Richard Tateson British Telecomms

Funds may be available to assist with travel and accommodation. For further details please contact Mrs Helen Forster, CytoCom Administrator, Department of Computer Science, University of Liverpool, Telephone: 0151 794 3670 Fax: 0151 794 3715, email: hff@csc.liv.ac.uk.

The UK CytoCom Network is funded by the EPSRC.

Nonlinear Dynamics in Control Theory

5 March 2001, School of Mathematical Sciences, University of Exeter

The aim of this meeting is to establish and enhance communication between the Control community, in particular Nonlinear Control Theory, and the Dynamical Systems community, in particular Bifurcation Theory. The idea is to formulate control problems in terms of a parameter-dependent "closed" dynamical system and focus on the control theoretical interpretation of the results obtained in this setting.

This workshop is sponsored by the LMS Southern Bifurcations joint research group.

The programme is not fixed yet, but will include Ludwig Arnold (Bremen) as one of the invited speakers. For more information, see http://www.ma.ic.ac.uk/~jswlamb/sbtg.html and/or http://www.maths.ex.ac.uk/~hinke/DSC/events.html.

Gordon Research Conference: Nonlinear Science

17-22 June 2001, Mount Holyoke College, South Hadley, Massachusetts USA

We wish to announce a new Gordon Research Conference in NONLINEAR SCIENCE. This will be an interdisciplinary conference focusing on applications of the methods and concepts from nonlinear dynamics to all areas of science. Special emphasis will be on experimental nonlinear systems, development of nonlinear applications and devices, and development of new nonlinear techniques aimed at addressing scientific issues.

The inaugural meeting of the GRC on Nonlinear Dynamics will cover a broad range of topics, although future meetings will have themes (determined by the conferees). Examples of topics for the 2001 conference include spatiotemporal dynamics, biological systems, fluid dynamics, dynamical systems theory, optical and solid states systems, complex systems, data analysis. We will also have several "outreach sessions" linking nonlinear dynamics with other areas of science.

Future mailings will follow with information on the program, submitting abstracts to be considered for short talks and posters, and application to Gordon Research Conferences to attend the meeting.

For further information please contact Ken Showalter ( kshowalt@wvu.edu) or Lou Pecora ( pecora@avnil.nrl.navy.mil) or visit the Gordon Research Conferences web site: http://www.grc.uri.edu.

Integrable Systems

July to December 2001, Newton Institute (Cambridge)

The modern theory of integrability was created and developed over the last thirty years by a number of international research groups. Several approaches to integrable equations have been elaborated, which look quite different but focus on solutions of the same range of problems. One of the aims of this programme is to bring together key scientists with various background and expertise in order to elaborate a coherent view on the problem and to attempt to develop a synthetic theory which would reconcile the different approaches. This will be the first meeting on such a scale and we expect that mutual understanding of different approaches will cause a breakthrough in the whole theory of integrable equations and significantly extend its applications.

The following methods for studying integrability will be discussed

In addition the "dressing method", and its many variations, will be looked at as a technique for constructing and solving integrable systems. The topic of Quantum Integrability will also be addressed. Links between the classical dressing method and various approaches to quantum systems will be studied. A fundamental issue is a classification of algebraic and differential reductions ``inside'' the integrable systems which have been constructed.
