There will be a special meeting of the North British Differential Equations Seminar on Friday 27th Feb 1998 to celebrate its 25th anniversary. The meeting will be in the Mathematics Department of University of Glasgow.
Professor John Ball FRS (Oxford) will present a lecture at 4:30 pm, title and abstract as below.
The start of the modern era of the calculus of variations was the posing and solution of the brachistochrone problem by Johann Bernouilli in 1696. The lecture will begin with a modern discussion of the brachistochrone problem, and then chart a selective path through some of the great contributions to the subject, leading to a discussion of current developments and possible future trends.

|WAVE - a wavelet based test for nonlinearity|
We examine general stationary ARCH models. Although the memory structure of ARCH sequences can be arbitrarily close to long-memory structure, we show that, in general, ARCH sequences exhibit short memory and satisfy the Central Limit Theorem. We compare ARCH models with other short and long-memory models.
We propose a test for non-linearity based on information contained in the wavelet coefficients on different scales obtained from a fast wavelet transform of the Daubechies type. The operational characteristics of the procedure are assessed, and we demonstrate the power of the WAVE test against non-linearities motivated by economic theory.

The International Conferences on Numerical Combustion, organised by SIAM, are the premier world forum for the theory and modelling of combustion processes. In spite of its name, the conference includes non-numerical matters as well as numerical issues, so that it has a very broad mathematical focus. The 7th conference in the series is being organised in York by the new UK and Ireland section of SIAM and has attracted an impressive range of contributions.
The programme for the conference is now complete. It includes 6 plenary lectures, 9 minisymposium sessions (36 presentations), 115 contributed presentations, and 9 poster presentations over the three days. Details are provided on the conference web pages at http://www.ma.umist.ac.uk/ICNC7/. The quality and scope of the papers to be presented promise to make the three days an enjoyable and stimulating scientific occasion.
Registration fees have been kept low, and are especially low for students, with reductions available for members of SIAM and other bodies cooperating in the organisation of the conference. Details of registration fees, and forms for registration are available electronically, or can be obtained by contacting the organisers. The address and other contact details are given below.
Contributions cover all of the main current questions and activities in Combustion Theory, arranged around the themes:
Minisymposia have been organised around the topics:
The six plenary lectures are:
|Philip Colella:||Adaptive Numerical Methods and Models for Low-Mach Number Combustion|
|Anne Dowling:||Thermo Acoustic Oscillations|
|Rupert Klein:||Numerical Techniques for Low-Speed and High-Speed Premixed Combustion|
|Takashi Niioka:||Stretch-Extinction and Radiation-Extinction of Counterflow Premixed and Diffusion Flames|

The third meeting of The UK Spatially Extended Dynamics Organisation (TUXEDO) is planned for Friday 24 April 1998 in the School of Mathematical Sciences, Queen Mary & Westfield College, London, supported by the LMS. Details will be available at http://www.damtp.cam.ac.uk/user/nlc.
The INLN (Institut Nonlinéaire de Nice) organises an annual summer school on nonlinear phenomena held in Peyresq (a small village in the French Alps). This year it will run from Monday 1st June to Saturday 6th June, 1998.
The theme this year is Conservative Systems. There are 4 courses whose provisional titles are:
The School is designed to be interdisciplinary: the first two courses are given by physicists, the other two by mathematicians, and the school is aimed primarily at Ph.D. students and young researchers, but more experienced researchers are very welcome; the school provides an opportunity to learn about developments in fields adjacent to their own.

We consider systems of linear differential/ difference-equations which have a quasi-periodic dependence in the unknown variable - often thought of as ``time''. These systems have a multiplicative part consisting of multiplication by a quasi-periodic scalar or matrix and a differential/difference part.
Two kinds of perturbation theory can be considered. If the multiplicative part is very small we perturb from a constant coefficient system which can be solved explicitly. In this case the aim of the perturbation theory is to construct quasi-periodic solutions. The case when the multiplicative part is very large can often be thought of as having a very small differential/difference part, in which case we perturb from a pure multiplicative system. In this case one looks for ``localised'' solutions.
There is a common feature in these two problems: the unperturbed part is an operator with a dense point spectrum and the problem is to construct point eigenvalues or even a dense point spectrum for the perturbed operator. The basic difficulty in such a perturbation theory turns out to be how to control the ``almost multiplicities'' of the eigenvalues.
The standard example used in this lecture course is the discrete one-dimensional quasi-periodic Schröodinger equation. Other examples will also be discussed.
Important contributions for these problems have been made by Dinaburg-Sinai, Moser-Pöschel, Krikorian, Frölich-Spencer-Wittver, Chuleavsky-Sinai and others. References are provided in my paper ``One-dimensional quasi-periodic Schrödinger operators - dynamical systems and spectral theory'' in the proceedings from ECM2 in Budapest 1996.
Lecturer: Professor M.R. Herman, Directeur de recherche, CNRS, Université de Paris 7 et Ecole Polytechnique, France.
Invariant tori are a crucial feature of not only of Hamiltonian dynamics, but also of volume-preserving dynamics and even general dynamics. Hamilton's implicit function theorem in Frechet spaces provides an efficient and flexible setting in which to study the existence of such tori. It allows simple proofs of classical results, such as the existence of diophantine invariant lagrangian tori in Hamiltonian dynamics, as well as less classical, but very basic ones, such as the existence of codimension one translated diophantine tori in general dynamics. Many important applications, in the Hamiltonian as well as the volume-preserving context, are considered.

The field of dynamical systems is in constant evolution in many directions. This school focuses on interactions between discrete and geometric dynamical systems, and between dynamical systems, theoretical physics, and computer science. This summer school is followed by an international conference on the same topic.
Time will be reserved for tutorial lectures for specialised seminars and for informal discussions organised by the junior participants.
Participants are encouraged to propose seminars talk on their current work. Titles and abstracts should be submitted before April 30th.
There is no registration fee.
Minimal lodging costs are around 1100 FF in student dormitories. Financial support is available under exceptional circumstances only. Further information is available on request.

The Centre de Physique Th\'eorique and the Institut de Math\'ematiques de Luminy are planning (subject to agreement from the appropriate authorities) to organise a conference in Marseilles from 6th to 10th July 1998.
This conference will focus on the interactions between discrete and geometric dynamical systems, and between dynamical systems, theoretical physics and computer science.
Modelisation of some physical phenomena with regularity and auto-similarity properties; e.g tiling problems and fractal sets. The mathematical tools: symbolic dynamical systems, formal languages, and more precisely substitutions and their multidimensional generalisations. The physical properties of quasicrystals are described in term of quantisation involving the C*-algebra of observables. Their spectral properties may be classified in term of K-theory, Cantor spectrum, scaling laws and spectral exponents.
Statistical and ergodic properties of dynamical systems. Applications to non-linear physics, with a particular interest in stability, chaos, turbulence and multifractal analysis of complex systems.
Symbolic systems associated with a geometric system (coding problems), and, the more difficult, converse problem of geometric representation of symbolic systems. The case of two commuting transformations, one having a chaotic behaviour and the other an almost periodic structure (geodesic and horocycle flow, substitution and adic system).
