MARY CARTWRIGHT MEETING

Friday 27 February 2009

Clore Lecture Theatre, Department of Mathematics, Imperial College London

3.30 Opening of the Meeting
 
Simon Donaldson, FRS (Imperial College London)
A spectator’s commentary on symplectic topology
 
The talk will survey some of the developments of modern symplectic topology over the past 30 years, aimed at non-specialists. We will discuss the developments of pseudoholomorphic curve techniques, Floer homology, connections with geometric topology in 3 and 4 dimensions and the theory of complex algebraic surfaces.
 
4.30Tea
 
5.00 Mary Cartwright Lecture
Dusa McDuff, FRS (Barnard College, Columbia University)
Symplectic embeddings of 4-dimensional ellipsoids
 
Gromov’s celebrated nonsqueezing theorem of 1985 says that it is impossible to embed symplectically a large ball into a thin cylinder. One of the foundational results of modern symplectic topology, this led to a more or less complete solution of the 4-dimensional symplectic packing problem (which asks when a given disjoint union of balls can be symplectically embedded into another ball). However, there are many other packing problems. In this talk we discuss recent joint work with Schlenk about the constraints on embedding a symplectic ellipsoid into a ball. This leads to some intriguing elementary questions in number theory. The result has applications to constructing 6-dimensional manifolds with symplectic circle action.
 
The talk does not use much symplectic topology and will be accessible to graduate students and nonspecialists.

A reception and dinner will be held after the meeting. Contact Susan Oakes (susan.oakes@lms.ac.uk) for further information.

There are limited funds available to contribute in part to the expenses of members of the Society or research students to attend the meeting. Contact Isabelle Robinson (isabelle.robinson@lms.ac.uk) for further information.

MATHEMATICAL MODELS OF COLLECTIVE DYNAMICS IN BIOLOGY AND EVOLUTION

An international conference and LMS workshop on Mathematical Models of Collective Dynamics in Biology and Evolution (MDBE’09) will take place at the University of Leicester from 11 to 13  May 2009 organised by Sergei Petrovskii (Leicester).

The conference will address the challenges that have risen from the recent development in life sciences, especially in cancer modelling and other collective dynamics such as population dynamics, ecology and epidemiology, and in the theory of evolution. The goal of the meeting is to make a synopsis of the most important recent findings in these fields, to reveal the inherent relation between the mathematical techniques most successfully used for problems of different biological origin, to emphasize the generic mathematical tools and the most effective ways of using them to address biological problems, and to identify the problems where groundbreaking developments can be expected in near future through application of recent mathematical advances in neighbouring fields.

The scope of the conference is outlined by (although not necessarily restricted to) the following topics:

  • ecology and epidemiology
  • interface between ecology and evolution
  • pattern formation and morphogenesis
  • collective cells dynamics and applications to tumour growth

The talks are expected to be mostly grouped around these subject areas. However, the organisers are ready and willing to consider any submission of a potentially high scientific merit which does not exactly fall into the list above. Confirmed plenary speakers are:

  • Daniel Grunbaum (Seattle, USA)
  • Alan Hastings (Davis, USA)
  • John King (Nottingham, UK)
  • Anatoly Neishtadt (Loughborough, UK)
  • Ezio Venturino (Turin, Italy)

In order to encourage wide participation of PhD students as well as early-career researchers, there will be a poster session organised during the conference. For UK research PhD students, partial financial support is possible to contribute to the travel or accommodation expenses.

To register send a message to sp237@le.ac.uk (Sergei Petrovskii) with a title and a brief abstract of your presentation (one page at most, in a camera-ready format, either pdf or Word), clearly indicating whether it is intended to be a talk or a poster. Also, in case there is more than one author, please indicate very clearly who is actually going to present the work.

The registration and abstract submission deadline is 1 March, and the decision of acceptance will be made by 15 March 2009. There will be a small registration fee of £50 to be paid in cash upon arrival. This event is supported by the London Mathematical Society and the University of Leicester.

Members of the Advisory Scientific Committee are: Alexander Gorban (Leicester, UK), Michel Langlais (Bordeaux, France), Philip Maini (Oxford, UK), Horst Malchow (Osnabrück, Germany), Jonathan Sherratt (Edinburgh, UK), Nanako Shigesada (Kyoto, Japan), Vitaly Volpert (Lyon, France).

MICHAEL FARADAY PRIZE LECTURE

The Royal Society Michael Faraday Prize Lecture will be given by Professor John Barrow, FRS (University of Cambridge) on Tuesday 24 February 2009 at 5.30 pm at The Royal Society, London.

This lecture is free – no ticket or advanced booking required. Doors open at 4.45 pm and seats will be allocated on a first-come-first-served basis. This lecture will be webcast live at http://royalsociety.org/live and available to view on demand within 48 hours of delivery.

Abstract. We look at the role of pictures and images in the development of science. From the first graphs and illustrated books to Molscript, the influence of the first pictures of spiral galaxies on Van Gogh’s ’Starry Night’, to the artistic resonances of the Hubble Space Telescope’s images, the mushroom cloud of the atomic bomb, and the intricacy of fractals, we will see how pictures have influenced science and spearheaded its communication to the public today.

SOUTH-WEST UK ANALYSIS MEETING

The South-West UK Analysis Meeting will take place on 21 January 2009 at the University of Bath. The meeting is thought of as a start-up initiative on the programme of building a regular forum for mathematical analysts based in the South-West of the UK, which includes Aberystwyth, Bath, Birmingham, Bristol, Cardiff, Oxford, Swansea. Although it is focused on the South-West analysis community, mathematicians from other parts of the UK are very welcome to attend.

The main idea behind the meeting is to bring together analysts working in the above research centres, which have formed during the last year or two but have so far had few chances to establish research links between themselves. The ’day’ will start around 10-11 am and finish about 5-6 pm, and will include five talks by distinguished analysts from the UK and abroad, lunch and two one-hour coffee/discussion breaks, to provide plenty of opportunity for interactions. The list of confirmed speakers is as follows:

  • Marc Briane (INSA, Rennes) Homogenisation and its applications to solid mechanics
  • Gianni Dal Maso (SISSA, Trieste)  Analysis of nonlinear PDEs, Calculus of variations
  • Patrick Gérard (Université Paris-Sud) Harmonic analysis, Semi-classical techniques
  • Frederic Klopp (Université Paris 13)  Mathematical Physics, Spectral analysis
  • Jim Wright (University of Edinburgh) Harmonic analysis, Number theory

The January 2009 meeting is supported by the LMS. Those wishing to attend please email CherednichenkoKD@cardiff.ac.uk.

SPARSE MATRICES FOR SCIENTIFIC COMPUTATION

In Honour of John Reid’s 70th Birthday

The Numerical Analysis Group at the Rutherford Appleton Laboratory is organising a two-day meeting to bring together leading numerical analysts from the UK and abroad in honour of John Reid’s 70th birthday. John is an eminent UK numerical analyst who, over a career spanning five decades, has made many important contributions, particularly in the development of sparse matrix technology. His main contributions include: conjugate gradients as an iterative method, Markowitz’ pivoting for sparse matrices, estimating sparse Jacobians, factorizing and updating linear programming bases, steepest-edge simplex algorithm, the multifrontal method for sparse linear systems, using 2 x 2 pivots for sparse symmetric indefinite matrices, and ordering sparse matrices for small wavefront and profile.

Since 1969, John has been a member of the Numerical Analysis Group (www.cse.scitech.ac.uk/nag) that began at the Harwell Laboratory and moved to the Rutherford Appleton Laboratory in 1990. One of the key activities of the Group and one for which it is internationally renowned is the HSL (www.cse.scitech.ac.uk/nag/hsl/hsl.shtml) mathematical software library (formerly called the Harwell Subroutine Library).  Amongst its best-known packages are those for solving sparse linear systems, optimization and sparse eigenvalues. Over the years, John has contributed to all these areas and many of his algorithms and packages are widely used today.

The meeting will be held over two days, from 15 to 16 July 2009 at Abingdon, Oxford. All talks will be by invitation.  Speakers will include:

  • Andrew Cliffe (University of Nottingham)
  • Jack Dongarra (University of Tennessee)
  • Iain Duff (Rutherford Appleton Laboratory)
  • Al Erisman (Seattle Pacific University)
  • Roger Fletcher, FRS (University of Dundee)
  • Shaun Forth (Cranfield University)
  • Sven Hammarling (NAG)
  • Kaj Madsen (Technical University of Denmark)
  • Nancy Nichols (University of Reading)
  • Beresford Parlett I (University of California)
  • Michael Powell, FRS (University of Cambridge)
  • John Reid (Rutherford Appleton Laboratory)
  • Michael Saunders (Stanford University)
  • Jennifer Scott (Rutherford Appleton Laboratory)
  • Nick Trefethen, FRS (Oxford University)

On Day 1, the talks will be related to the areas of numerical analysis that John has been involved in over his long career. These will include optimization, sparse direct methods, numerical linear algebra, iterative methods, and automatic differentiation.

Day 2 will concentrate on algorithms and software for large-scale systems. It will include talks by leading experts on the history and importance of mathematical software libraries, and look to the future and to new challenges for such libraries. Particular emphasis will be placed on software for sparse problems that has been developed by the Numerical Analysis Group and is used to solve practical problems from a range of application areas.

A celebratory dinner will be held on the evening of the first day. Further details are available at www.cse.scitech.ac.uk/nag/ or by contacting jennifer.scott@stfc.ac.uk. The meeting is being supported by an LMS Conference grant.

THE UK GRADUATE MODELLING WEEK

LMS–EPSRC Short Course

University of Nottingham, 23–27 March 2009

Organiser: Professor John Billingham

Course outline and prerequisites

The key skills needed to cut through the fog of detail that surrounds a typical industrial problem, formulate a useful mathematical model, and then analyse and refine it, are not taught in most UK mathematics degrees. This course will teach these skills through a week of practical problem solving in small groups. The format will closely follow that of the annual UK Study Group with Industry (www.maths-in-industry.org/), except that the problems will be presented by experienced instructors, who will then guide the participants for the remainder of the week. We hope that all participants will go on to attend the full Study Group, which will be held at the University of Southampton during the following week. The instructors and problems will be:

  • Chris Breward (Oxford)  Diffusion in the human eye
  • Chris Coles (Strathclyde)  Pollution cleanup in a pipe network
  • Giles Richardson (Southampton)  Modelling the behaviour of batteries
  • Jonathan Wattis (Nottingham)  Uptake of fatty particles by the liver
  • Eddie Wilson (Bristol)  Ultrasound positioning devices

Previous knowledge of any of these topics is not a prerequisite, and is much less important than enthusiasm and an open mind.

Application

Applications should be made using the registration form available on the Society’s website at: www.lms.ac.uk/activities/rmc/sc/44poster.html. Applicants should indicate their background and interests, so that they can be assigned to an appropriate group.

The closing date for applications is Friday 30 January 2009. Numbers will be limited and those interested are advised to make an early application.

Fees

  • All research students registered at a UK university will be charged a registration fee of £100 (in the case of EPSRC-funded research students, this fee should be paid by their departments from their Doctoral Training Account; for non-EPSRC research students, their department might be prepared to pay the fee). They will not be charged for subsistence costs.
  • UK-based postdocs will be charged a registration fee of £100, plus half the subsistence costs (£180).
  • All other attendees (overseas students and postdocs, those working in industry) will be charged a registration fee of £250 plus the full subsistence costs (£360).

All participants must pay their own travel costs (for EPSRC-funded students, this should be covered by their DTA). Fees are not payable until a place on the course is offered. In the event of over-subscription, preference will be given to UK-based research students.

Back to Top LMS–EPSRC Short Courses aim to provide training for postgraduate students in core areas of mathematics. Part of their success is the opportunity for students to meet other students working in related areas as well as the chance to meet a number of leading experts in the topic.

 

 





VARIATIONAL PROBLEMS IN DIFFERENTIAL GEOMETRY

An LMS and EPSRC sponsored research workshop on Variational Problems in Differential Geometry will be held at the School of Mathematics at the University of Leeds from 30 March to 2 April 2009.

  • Hamiltonian variational problems
  • Exceptional holonomy
  • Kähler metrics of constant scalar curvature

The format of the workshop will provide five one-hour lectures per day, by invited speakers, leaving generous breaks between talks for questions and informal scientific interaction. Speakers include:

  • Bernd Ammann (Regensburg)
  • Claudio Arezzo (Parma)
  • Paul Baird (Brest)
  • Olivier Biquard (Paris 6)
  • Christoph Böhm (Münster)
  • Francis Burstall (Bath)
