Subject: PDE Coffee Table Book

NA-Net colleagues,

We seek advice and contributions for an ongoing collaborative project,
the "PDE Coffee Table Book".

This book, which we hope to complete next year, is distantly inspired
by Van Dyke's classic, "An Album of Fluid Motion." Our plan is to
publish a colorful volume consisting of about 75 two-page spreads, each
about a different PDE. In each case we will hold to exactly two pages
that tell the reader as interestingly and as accurately as possible
what the behavior of this PDE is, where it arises, what interesting
mathematical features it possesses, and some of the key references.
Every page contains a figure, usually of a solution computed
numerically or photographed in the laboratory, and most of them are in
color. Our hope is that this book will help promote enthusiasm for
this beautiful and important subject among students and mathematicians
and scientists and engineers around the world, and help us all to see
connections between diverse topics.

This is a collaborative project coordinated by the Numerical Analysis
and Applied Mathematics groups at Oxford. So far, about fifty people
at Oxford and elsewhere have contributed draft pages. We ask:

(1) Would you be willing to serve as an "expert reader" to improve our
current draft of one of the equations in the attached list?

(2) Would you like to volunteer to draft a page on a PDE not in the list?

(3) Can you point us to any great images of solutions of particular
PDEs (or other sources, or other equations) that we may have missed?

All contributions will be acknowledged in the published book. We are
enjoying the process as well as the product! -- and are happy to hear
from any new colleagues who may wish to participate.

Please send responses to with a copy to With thanks,

Subject: MATLAB Interface to Adaptive Simulated Annealing

I received the email below from Shinichi Sakata, informing me that he

> Subject: MATLAB gateway routine to ASA

Dear Lester,

Asamin provides an interface (mex file) for using ASA within
MATLAB. With asamin, you call ASA from MATLAB to search the minimum
of an objective function coded in the MATLAB language. Asamin also
offers a way to change many of ASA's run-time options. You would not
need much knowledge about the C language to use asamin, unless you
want to use an array of compilation-time options available for ASA.

Asamin is written for and tested with MATLAB 5.3 on Solaris
2.5.1. In order to run it with other versions of MATLAB or on other
platforms, you may need to make some changes to its source code.

Asamin is available from

Subject: Conference on Parallel and Distributed Processing


The 2000 International Conference on Parallel and Distributed
Processing Techniques and Applications (PDPTA'2000),
June 26 - 29, 2000, Monte Carlo Resort, Las Vegas, Nevada, USA.

Session Title: Parallel and Sequential Algorithms for Numerical Solution of
Ordinary and Partial Differential Equations.

Aim and Scope:
The past years have witnessed the rapid development of Numerical Solution
of ODEs and PDEs. The present section of PDPTA'2000 is devoted to
researchers and developers interested in the following aspects of the subject:

1) Numerical methods for special types of equations (e.g. molecular
dynamics, celestial mechanics, quamtum mechanics) whose demands cannot be
satisfactorily provided by standard numerical solvers.
Experimental fitting tecniques and methods based on Difference equations
are especially welcome.

2) Higher order accurate numerical methods and methods with
minimum computational cost and Numerical methods preserving qualitative
features of the flow ( e.g. symplecticity, unitaryness, isospectrality,
phase, etc).Development of new techniques that allow insight into
the behaviour of numerical methods.

3) Finite Difference and Finite Element Methods for the Numerical
Solution of Partial Differential Equations. Adaptive
strategies and solution of nonlinear equations.

4) Domain Decomposition Methods for Partial Differential Equations.
New algorithms and theory for domain decomposition methods for
parallel computing.

The emphasis in points 1)-4) is on techniques that aid in parallel solution
of problems.
