Workshop on Symmetry Methods for Differential and Difference Equations

Centre for Interdisciplinary Nonlinear Mathematics, Department of Mathematical and Computing Sciences, Surrey University

27-28 May 1997

Organisers: Prof Chris J Budd (Bath) & Dr Peter E Hydon (Surrey) Email: cjb@maths.bath.ac.uk & p.hydon@mcs.surrey.ac.uk.

It has long been recognised that many important partial differential equations (PDEs) arising in mathematical physics and applied mathematics are invariant to a Lie group of transformations. By exploiting this invariance, exact solutions can be determined in many cases. Remarkably, such solutions are often also global attractors for more general solutions of the equations satisfying various initial data. Symmetry also plays an important role in studies of ordinary differential equations (ODEs) that describe the evolution of systems on manifolds.

When differential equations are discretised, the symmetry properties are often lost and the resulting discrete solutions fail to capture important qualitative features of the underlying differential equation. Recently there has been much progress in developing numerical methods for both PDEs and ODEs which inherit the symmetry properties of the underlying system. Such methods afford the promise of capturing important qualitative information about the underlying differential equation over long time periods.

The purpose of the workshop is to bring together numerical analysts, analysts and applied mathematicians who are using symmetry-based methods to design numerical schemes and to find exact or similarity solutions of ODEs and PDEs. The workshop will have three sessions: (a) symmetry methods for PDEs, (b) symmetry methods for discretisations of ODEs and (c) symmetry methods for discretisations of PDEs. In addition to the invited lectures, there will be ample opportunity for discussion.

The meeting coincides with the visit to the UK of Prof. V. Dorodnitsyn from the Keldysh Institute, Moscow, supported by the FSU scheme of the London Mathematical Society Speakers will include:

Prof C. Budd (Bath), Prof P Clarkson (Kent),
Dr V Dorodnitsyn (Moscow),Dr V Galaktionov (Bath),
Dr P. Hydon (Surrey), Dr A Iserles (DATMP, Cambridge),
Prof J King (Nottingham), Dr E Mansfield (Kent),
Ms A. Zanna (DATMP, Cambridge)

This workshop is sponsored by: London Mathematical Society, EPSRC and the School of Electronics, Information Technology and Mathematics. There will be a 15 pounds registration fee and a fee of 47 pounds for accommodation and meals.

Funds are available to support interested participants -- contact the organisers for further information. Details and updated information about this workshop can be found at the website:

Advanced School, Workshop and Conference on Mathematical Models of Systems Involving Phase Changes: Dynamics of Mixed Phase Regions

The International Centre for Mathematical Sciences (ICMS), Edinburgh

2-20 June 1997

Scientific Committee
M E Glicksman RPI, New York
R N Hills Heriot-Watt, Edinburgh
H E Huppert Cambridge
C Jaupart IPG, Paris
D E Loper Florida State

This three week programme aims to bring together leading workers from different disciplines: mathematicians; geophysicists; experimentalists; and metallurgists; to encourage a cross-fertilisation of approaches. The event includes a seven-day International Workshop dealing with macroscopic manifestations of solid-liquid mixed phase systems together with a three-day Conference on the Dynamics of Mixed Phase Regions. Throughout, the primary goal will be to identify the dominant physical processes and so determine the correct macroscopic equations and boundary conditions that relate to phase-changes in a variety of both pure & multi-component systems. The programme will be founded on a core of about ten scientists drawn from various disciplines and, during the first week, these researchers will contribute to an instructional programme for young scientists. The workshop, beginning in the second week, will specifically concentrate on the topics of phase coarsening, convection, compaction, magmas, mushes/slurries, computer and phase field models.

Participants include:

C. Beckermann (Iowa) D. McKenzie (Cambridge)
C.F. Chen (Arizona) O. Penrose (Heriot-Watt, Edinburgh)
P.C. Fife (Utah) R. Sekerka (Carnegie-Mellon)
A.C. Fowler (Oxford) S.R. Tait (IPG, Paris)
D.T.J. Hurle (Bristol) P.W. Voorhees (Northwestern)
A.A. Lacey (Heriot-Watt, Edinburgh) A.W. Woods (Bristol)

Up to date details can be found on the web site: http://www.ma.hw.ac.uk/icms/1997/school.html.

The proceedings will close with a broadly based, three day Conference embracing other phase-change systems.

The Conference will be devoted to a study of the novel phenomena associated with dynamic, partially solidified systems. It will be concerned with both the theoretical modelling and the physical occurrences of mushes, slushes and slurries. In addition to the talks given by the main lecturers listed below, short communications, limited to 20 minutes with 5 minutes discussion, will be organised.

Invited speakers include:

S.H. Davis (Northwestern) H.M. Tensi (Munich)
L. Ratke (Cologne) J. Wettlaufer (Washington)
P.H. Roberts (UCLA) M.G. Worster(Cambridge)

Provisional Time Table for each Day
08:45 - 10:00 First plenary speaker
10:00 - 10:30 Coffee
10:30 - 11:45 Second plenary speaker
11:45 - 13:00 Third plenary speaker
13:00 - 14:00 Lunch
14:15 - 15:30 Fourth plenary speaker
15:30 - 16:30 Tea and Poster Session
16:30 - 17:30 Discussion Session

Some benefits of the planned meeting

  1. A semi-formal workshop atmosphere.
  2. Plenary speakers given adequate time.
  3. No parallel sessions.
  4. A rare chance to get to know people in related disciplines.
  5. Plenary speakers will select key posters during the meeting and hence encourage new talent.
  6. Participants in the different days will be carefully chosen to be able to contribute as an active audience to the other days.

The plenary speakers for each day are requested to choose one (or at most two) poster presenters in their general field and supportively chair them through five minute talks during the Discussion Session. Poster presenters (probably about 20 per day) are therefore required to have copies of their poster pages on overhead sheets. This innovation worked very well at the last International Meeting of the Centre for Mathematical Biology at the University of Bath. This was organised by NFB, NRF and ABSF, among others, and held in April 1996.

The venue of the meeting

Bath is one of Europe's most beautiful small cities and is also only 80 minutes from London by train. The University of Bath is one of the UK's most successful small Universities. (It ranked sixth overall in the recent National Research Assessment Exercise.) It is situated on an attractive campus, neighbouring open countryside, yet is only one mile from Bath city centre. On campus, the University of Bath has some of the best sporting facilities of any British University, many of which are available to conference participants. The 120-seat lecture theatre earmarked for this meeting is one the University's newest (being completed just two years ago) and is extensively equipped with audio-visual aids. A larger lecture theatre should be available if demand is greater.

Accommodation on campus will be available for people attending the conference. Current accommodation costs (B&B) are 19 pounds per night for standard rooms and 25 pounds per night for en suite rooms. Current costs for lunch are 6.80.

Registration Fees will be 30 pounds per day or 100 pounds for four days, with reductions for students.
