UK Nonlinear News, February 2001



Professor Robert MacKay elected to the Fellowship of the Royal Society

UK Nonlinear News would like to congratulate Professor Robert MacKay on his recent election to the Fellowship of the Royal Society.. 

Professor MacKay's main achievements have been the discovery of a renormalisation fixed point governing the breakup of invariant circles for area-preserving maps and a sliding-pinning transition in solid-state physics, the construction of surfaces of locally minimal flux governing transport in Hamiltonian systems and the development of a rigorous criterion for non-existence of invariant tori. These studies together with major developments in Hamiltonian dynamics have deepened our understanding of a wide variety of topics including chaotic behaviour and equilibrium states of systems with strong electron-phonon coupling. He is currently Director of Mathematical Interdisciplinary Research, Mathematics Institute, University of Warwick


Visit of Professor Constantine M. Dafermos to Oxford University

Professor Constantine M. Dafermos (Brown University) will visit the Mathematical Institute, Oxford University, from January to June 2001. While at Oxford he will give a six lecture course (Tuesdays 3-4, beginning 30 January) on

Hyperbolic Conservation Laws in Several Space Dimensions

ABSTRACT: Quasilinear hyperbolic systems of partial differential equations in divergence form, commonly called "hyperbolic conservation laws", occupy a central position in mathematical physics. Despite recent major progress in the theoretical and numerical treatment of such systems, the analysis in the multi-spatial situation still faces insurmountable obstacles. The lectures aim at presenting what is already known (rather little!), what would be desirable to find out and why it is so difficult to achieve it.

Two new Chairs in Mathematics at the University of Surrey

As part of the overall commitment to expansion of applied mathematics, with particular emphasis on the interface between pure and applied mathematics, the University of Surrey has appointed two new Chairs in Mathematics: Ian Melbourne and Mark Roberts. Ian and Mark will take up their posts in March 2001. Some background on the new appointments is below. 

Ian Melbourne was an undergraduate at the University of Manchester, and was awarded a PhD by the University of Warwick in 1987, supervised by Professor Ian Stewart. Immediately thereafter, he took up the position of Assistant Professor at the University of Houston, in the dynamics and symmetry group there. In 1993-4 he was a visiting Fellow at the Insitut Nonlineaire de Nice, Sophia Antipolis. He was subsequently promoted to Associate Professor and most recently in 1998 to Professor of Mathematics at University of Houston. His research interests include dynamical systems with symmetry, global dynamical systems, Ginzburg-Landau theory and other modulation equations, pattern formation with Euclidean symmetry, ergodic theory, bifurcation theory, and symmetric chaos. 

Mark Roberts was an undergraduate at the University of Oxford, and was awarded the PhD by the University of Liverpool in 1983, supervised by Professor Terry Wall FRS. Subsequently he was a postdoctoral research fellow at IHES, France; University of Southampton; and University of Houston. In 1985 he was awarded a 5 year EPSRC Advanced Fellowship at the University of Warwick. He took up a Lectureship in Mathematics at Warwick in 1988, and was promoted to Senior Lecturer in 1999. His research interests include equivariant singularity theory, Hamiltonian systems and symplectic geometry, theory of mechanical systems with symmetry such as molecules, rigid bodies and atomic nuclei, structure of Lie groups, symmetric chaos, and relative equilibria, with applications to galaxy formation, bubbles, and vortices.

Stephen Wiggins appointed Professor at Bristol University

Stephen Wiggins is taking up his appointment as Professor of Applied Mathematics with the Applied Mathematics and Numerical Analysis Group of the Department of Mathematics, Bristol University, from early February 2001.

Stephen Wiggins was a faculty member at the California Institute of Technology since 1985, following his Ph.D. at Cornell. Initially he was von Karman Instructor in Applied Mathematics, then Assistant Professor of Applied Mechanics in 1987, Associate Professor in 1992; and most recently as Professor of Applied Mechanics, and Control and Dynamical Systems since 1994.

Professor Wiggins' principal research interests are in the fields of theoretical nonlinear dynamics, fluid mechanics and theoretical chemistry, and his work on the physical applications of dynamical systems theory to a wide range of science and engineering problems has won him an international reputation as a leading applied mathematician.

He publishes extensively, with some 60 articles in refereed journals to his name as well as eight books - both advanced textbooks and research monographs - in print or in production. He is the Managing and Founding Editor of the Journal of Nonlinear Science.

Chaos theory and social services

I am trying to write a paper about beliefs about causality as they influence social policy at a macro level and decision making in social work at a case level. (e.g. the belief that child abuse is caused linearly by one factor - poor parenting - or many - a combination of factors favoured by different professions) and how new theories of causality could change practice. Are you aware of people/institutions looking at the possibility of non-linear systems being behind aspects of human behaviour? I'd be grateful for any pointers.

Mailing list: Nonlinear Chemical Dynamics

We have established a listserver for the exchange of information on nonlinear chemical dynamics, which currently has over 300 participants from 20 countries.

The goal of the list is to provide a forum for the discussion of current topics in nonlinear chemical dynamics, including (but not restricted to) chemical oscillations, waves, fronts, self-organization, fractals, chaos, etc.

You may use it to ask questions about experimental and numerical methods, to advertise conferences and job openings in the field, or to let the community of some recent publication that may be of interest. Experts, neophytes and the generally interested are encouraged to subscribe.

To subscribe to the list, you can send a message to john@pojman.com requesting to be added or send a message to list@wave.st.usm.edu. In the first line of the body of your message put

Obituary: Jürgen K. Moser (1928-1999)

Jürgen K. Moser made deep and important contributions to an extremely broad range of questions in dynamical systems and celestrial mechanics, partial differential equations, nonlinear functional analysis, and the calculus of variations. A memorial article written by John N. Mather, Henry P. McKean, Louis Nirenberg. and Paul H. Rabinowitz appears in Notices of the American Mathematical Society 47 (11), 1392-1405. John Mather treats KAM theory, Louis Nirenberg describes Moser's work in partial differential equations, and Henry P. McKean writes about completely integrable Hamiltonian systems.


Web: Navier-Stokes equations net

I would like to draw your attention to a specialist web site devoted to Navier-Stokes equations and related non linear PDE problems

http://wwwlma.univ-bpclermont.fr/NSenet/

This web site was written by Didier Bresch and Pascale Lefort in collaboration with Giovanni Paolo Galdi. It aims to connect researchers who work in the field of the Navier-Stokes equations from a mathematical, engineering and computational point of view.

The site contains a repository for preprints and links to a range of scientific outputs including "Conferences", "Journals", "Lecture Notes", "Book-Reviews", "Ph.D. Thesis Summaries", and "Simulation Packages". It is likely to be a useful source for graduate students or young researchers who are starting to work on fluid flow problems.

It is hoped that the web site (and associated mailing list, NSelist) will become a forum where senior researchers will bring their knowledge and expertise on topics related to the Navier-Stokes equations. It is also hoped that the web site will be a reference point for Industries and Companies that would like to be informed about what it is accomplished in the Universities all over the world, on mathematical and computational aspects of fluid mechanics.
