This meeting will discuss recent developments and techniques for finding and studying the dynamics of travelling fronts, with particular interest in the implications for fronts in biological problems. The list of speakers at the workshop will include

The workshop will commence at midday. We expect to be able to cover lunch plus trainfare for all interested participants. For further details contact the organisers. Updates on the workshop schedule will be posted at the Centre website:


School of Mathematical Sciences, University of Nottingham Wednesday 16 September 1998

This workshop forms the fourth and final meeting of the London Mathematical Society Scheme 3 program on bifurcation and symmetry. The meeting will focus on some of the many applications of bifurcations with symmetry. The aim is to bring together workers in these fields and experts in the more theoretical aspects of bifurcation and symmetry. This has proved to be mutually beneficial in the past and it is hoped to extend the connections established in the related previous LMS meetings.

Prospective speakers should contact Paul Matthews

( ) with a title before 14th August.

Further details of the meeting will be posted on the WWW at

On Growth and Form: Spatio-Temporal Patterning in Biology
Centre for Nonlinear Systems in Biology

University of Dundee

20 - 24 September 1998

An international meeting supported by the Society for Mathematical Biology, the European Society for Mathematical and Theoretical Biology, SmithKline Beecham Bioinformatics, the London Mathematical Society, the Edinburgh Mathematical Society, the British Society for Developmental Biology.

The meeting will mark the occasion of the 50th anniversary of the death of D'Arcy Wentworth Thompson and the topics under discussion at the meeting will be pattern formation in developmental biology, pattern formation in reaction-diffusion systems, pattern formation in intercellular systems, pattern and form in morphometrics.

Local Organising Committee: M.A.J. Chaplain, J. Crawford, P. Smith, C. Weijer, S. Hubbard, R. Herbert, G.D. Singh, P. Slater (St. Andrews), J. McLachlan (St Andrews)

Scientific Advisory Committee: J.D. Murray, L. Wolpert, B. Goodwin

The meeting will begin on Sunday 20th September 1998, finishing on Thursday 24th September 1998. The meeting will evolve by focusing in turn on each of the following topics:

On the Growth of Form
On the Mathematics of Form
On the Dynamics of Form
On the Description of Form
On the Form of Form

The daily programme will consist of plenary talks, workshop sessions, poster presentations and discussion sessions. Each day will focus on one of the topics listed above and the invited talks will be of 45minutes in length, with an additional 15 minutes allocated for a short question/discussion period. There will be three plenary talks, of one hour duration, during each morning session punctuated appropriately with a coffee/tea/refreshment break. After lunch there will be a workshop session which will take the format of a poster presentation session open to all other participants. The final plenary talk will immediately be followed by a discussion session. We would expect and strongly encourage a significant number to be graduate students and young post-doctoral researchers. A limited amount of financial support from the Society of Mathematical Biology to assist participation by graduate students is available. Full details are given below.

There will also be a permanent display of specimens from the University's D'Arcy Thompson Museum throughout meeting.
