David Chillingworth (Southampton) awarded LMS Scheme 3 grant

David Chillingworth have recently been awarded an LMS Scheme 3 grant of 750 pounds (1000 pounds) to organise three (four) meetings on the topic of BIFURCATION AND SYMMETRY. Supporters of the grant are: Peter Ashwin (Surrey), Jacques Furter (Brunel), Paul Matthews (Nottingham), Mark Roberts (Warwick) and Anne Skeldon (City).

It is proposed to hold meetings in 1998 approximately as follows:

January, Southampton, Bifurcation geometry
June, Warwick, Relative equilibria
September, Nottingham, Applications in mechanics

with one additional meeting probably in London.

Organisation is still in progress. For further information contact

SIAM Student Paper Prizes

The annual SIAM Student Paper Prizes will be awarded during the 1998 SIAM Annual Meeting, July 13-17, at the University of Toronto.

The authors of the three best papers in applied and computational mathematics written by students and submitted to SIAM will present their papers at the meeting and will receive a $750 cash prize as well as gratis registration for the meeting. The winners will be awarded calligraphed certificates at a special prize ceremony at the meeting. To be eligible for consideration papers must be singly authored and not previously published or submitted for publication. To qualify, authors must be students in good standing who have not received their PhDs at the time of submission.

In submitting their work for publication, authors are asked to consider SIAM journals. However, student paper prize winners are not guaranteed publication in any SIAM journal; all papers submitted to SIAM journals are subject to the same refereeing process and standards.

Submissions must be received in the SIAM office on or before March 15, 1998.

Submissions, which must be in English, can be sent by regular mail or fax. Each submission must include (1) an extended abstract NOT LONGER THAN 5 PAGES (including bibliography); (2) the complete paper, which will be used solely for clarification of any questions; (3) a statement by the student's faculty advisor that the paper has been prepared by the author indicated and that the author is a student in good standing; (4) a letter by the student's faculty advisor describing and evaluating the paper's contribution; and (5) a short biography of the student.

Submissions will be judged on originality, significance, and quality of exposition.

The winners will be notified by June 1, 1998.

Please direct your submission and any questions you may have to A. Bogardo at SIAM, 3600 University City Science Center, Philadelphia, PA 19104-2688; telephone (215) 382-9800; e-mail to; fax to (215) 386-7999.

Royal Society of London Postdoctoral Fellowship awarded to Mark Nelson

Mark Nelson of the University of Leeds has been awarded a Royal Society of London postdoctoral fellowship to pursue work at The University of Auckland on the mathematical theory of ignition. The two particular foci of this work will be on modelling the fire hazard posed by polymers and the phenomenon of catalytic enhanced ignition. In the latter a catalyst is used to set up heterogeneous reactions which are generally at lower temperatures than in a conventional premixed burner and the heat from which is transferred mainly through radiation. Catalytic combustion is a relatively new science.

Dr Nelson is currently a researcher in the Department of Fuel and Energy and the Centre for Nonlinear Systems in the University of Leeds. He completed his PhD there a couple of years ago and has worked on polymer ignition since that time. The Fellowship awards are for young British scientists to spend up to one year in New Zealand and are awarded on a competitive basis according to the track record of the appointee and the project specification. During his time here Dr Nelson will work with Professor Graeme Wake (Applied Mathematics) and Dr Dong Chen (Chemical and Materials Engineering) and their respective colleagues.

Visits and Visitors

Dr Jan Iwaniszewski visits Manchester and Lancaster

Dr Jan Iwaniszewski of the Nicholas Copernicus University, Torun, Poland, will be visiting A J McKane (Manchester) and P V E McClintock (Lancaster) for 12 months from 1 November 1997, supported by an EPSRC Visiting Fellowship. He will be based in Lancaster, and PVEMcC is happy to act as a contact if need be.

Dr Iwaniszewski is an expert on the escape of a system over a fluctuating barrier, a scenario of wide relevance in physics and chemistry. The point is that Kramers' celebrated formulation of the temperature-assisted barrier-crossing problem is insufficient for a correct description of systems whose dynamics is governed by widely varying timescales. During the barrier crossing event, the barrier itself may vary, being modulated by some relevant degree of freedom, often in a stochastic fashion. Examples include chemical reactions in liquids or between large molecules (e.g.~CO binding to h{\ae}m), transport processes in disordered media and through biomembranes, transmission of a signal in a perturbed medium, relaxation in glasses, movement of electrons in semiconductors through a time-varying insulating layer, dynamics of dye lasers, and some ratchet models for the action of molecular motors. It was this multitude of scientific contexts that gave rise to John Maddox's famous comment that ``the fluctuating barrier is a concept whose time appears to have come''.
