This medal is New Zealand's premier scientific honour and is awarded annually, in rotation amongst various sciences. It was named in memory of Sir James Hector, a pioneering New Zealand scientist, and amongst its recipients is Ernest Rutherford (1916). The last occasion when it was awarded to a mathematical scientist was in 1982 when the recipient was Roy Patrick Kerr, for his work in the theory of relativity. The Royal Society of New Zealand is that country's scientific academy and the award of the Hector medal this year is regarded by John as a recognition of the importance of numerical analysis. ------------------------------ From: Stanly Steinberg Date: Sun, 17 Nov 1996 23:53:58 -0700 (MST) Subject: Nonlinear PDE Examples Needed Dear Colleagues: I need some **realistic** examples of convection-diffusion or diffusion equations of the form d epsilon / d t = div(A.grad(f)) + div(V.f) + F where epsilon depends nonlinearly on f or A depends of f or both. I am particularly interested in the diffusion dominated case, e.g. examples where V = 0. I want to use the problems for test cases for finite-difference and finite-volume algorithms. Textbook references would be great.

QMG is free software available on the Web for fully automatic unstructured finite element mesh generation in two and three dimensions. It can generate meshes for complex polyhedral domains with nonmanifold features. It includes geometric modeling routines for polyhedral domains, two mesh generators and a finite element solver. QMG is written in primarily in C++ and is a collection of m-files and mex-files that run under Matlab 4.2. The new features of QMG1.1 (compared to QMG1.0) are: (1) In addition to running under Matlab, QMG1.1 can also run under Tcl/Tk. Tcl is a scripting language, and Tk is a GUI-building toolkit. Both were developed at UC-Berkeley/Sun Microsystems and are available on the Web. (2) QMG1.1 runs under Microsoft Windows NT as well as Unix. Windows NT (i386) users can download the QMG executables directly from the Web. (3) QMG1.1 uses VRML and a web browser for 3D graphics. (4) QMG1.1 includes a Delaunay-based boundary mesh generator as well as an octree-based volumetric mesh generator. (5) The 3D volumetric mesh generator in QMG1.1 runs much faster and produces higher quality meshes than QMG1.0. (6) QMG1.1 supports additional simplified file formats for I/O of geometric objects.

Stetter Date: Wed, 20 Nov 96 12:03:55 MET Subject: Special Issue on Symbolic-Numeric Algebra for Polynomials C a l l for P a p e r s Special Issue of Journal of Symbolic Computation on Symbolic-Numeric Algebra for Polynomials Within the area of Scientific Computing, the results of algebraic problems are often needed in numerical form to a specified accuracy. Some of the data of such problems (e.g. coefficients of polynomials) may be exact while others may be known only within a given tolerance. In such situations, the usual concepts and algorithms of computer algebra are not immediately applicable. Appropriate approaches must utilize ideas and algorithmic techniques from numeric computation together with standard and possibly extended procedures from classical computer algebra. The emerging area of mathematics dealing with this situation may be thought of as "numerical nonlinear algebra", in analogy with the well-known area of "numerical linear algebra". While some work in this field had already begun in the 1980s, activities have recently been growing in depth and breadth. This summer the workshop SNAP 96, held at INRIA Sophia Antipolis (France), brought a focus to the area of symbolic-numeric algebra for polynomials. The literature in this area has appeared in various locations, but has until now been quite dispersed and difficult to locate. It appears timely to collect some outstanding results of this development into a special issue of the Journal of Symbolic Computation. We invite submissions for this special issue on Symbolic-Numeric Algebra for Polynomials. Such papers should contribute to the understanding of the inter- action of symbolic and numeric computing. Their results should be relevant for the design of algorithms for the solution of related problems and the computer implementation of such algorithms. Relevant topics include, but are not restricted to: - GCD computation for polynomials with inexactly-known coefficients; - symbolic-numeric methods for simplifying and solving multivariate polynomial systems; - matrix methods oriented towards zero-dimensional ideals (e.g. multivariate resultants); - methods for other approximate polynomial problems (e.g. factorization, Pade approximation); - software systems for the efficient implementation of such algorithms, taking advantage of existing numerical libraries. Manuscripts should be submitted to either one of the two guest-editors who will handle the preparation of this special issue. Deadline for submission of full papers: 31 March, 1997 Notification of acceptance/rejection: 30 June, 1997 Final revised manuscripts due: 30 September, 1997 Appearance of special issue: early in 1998 Guest editors: Stephen Watt Hans J.

Like the 1996 conference in Lyon, the 1997 version will consist of a number of highly focussed workshops on all aspects of parallel processing, from theory to practice, from academy to industry. The workshops will present the latest advances in their respective domains. In addition, there will be a number of high-level tutorials of general interest plus a series of invited talks. All accepted papers will appear in the proceedings published by Springer-Verlag in the LNCS Series. Today, robust and efficient parallel algorithms for the basic problems of numerical mathematics are crucial for most of the computational work arising in science and engineering. Therefore, this workshop shall be a forum for the presentation and discussion of new developments in the area of parallel numerical algorithms, covering all aspects from the algorithmic idea and the software prototyping to the efficient implementation on modern parallel architectures and the performance analysis. Due to its significance in the field of partial differential equations and others, the solution of large linear systems will be in the centre of interest, but contributions concerning other problems from numerical linear algebra or topics like numerical quadrature, nonlinear systems, integral equations, or differential equations in general are very welcome, too.

For those of you who don't know of it, this is the largest computer algebra meeting, and is held yearly. It will be held in federation with PASCO (Parallel Symbolic Computation) '97 (July 20-22) and in association with the IMACS ACA (Applications of Computer Algebra) '97 (July 24-26), both at the same location. Assistance is being provided by the Maui High Performance Computing Centre. Numerical analysts and other readers of NA.Digest are especially invited to attend this meeting, which is sponsored by SIGNUM as well as by SIGSAM; some very exciting things are happening at the boundary between numerical and symbolic computation. The (very hard) deadline for paper submissions is January 15, 1997 and details on topics of interest, instructions for authors and the like may be found at the official ISSAC '97 web page: http://www.mcs.drexel.edu/ISSAC97 I hope to see you in Hawaii. ------------------------------ From: Robert Corless Date: Wed, 20 Nov 1996 13:04:23 -0500 Subject: SIGSAM Bulletin S I G S A M B u l l e t i n Communications in Computer Algebra Dear Colleagues: Many of you will have read Professor H. J. Stetter's recent letter in the SIGNUM newsletter, discussing the connection between numerical analysis and computer algebra. This note is to echo his invitation to numerical analysts to participate more fully in the area. In particular, as Editor of the SIGSAM Bulletin (SIGSAM = Special Interest Group in Symbolic and Algebraic Manipulation), a quarterly publication of the ACM, I would like to invite you to submit items for consideration for publication in the Bulletin. Items of interest could include calls for papers for conferences and special issues of various journals, preferably less than one page and in LaTeX2e. More interestingly, short papers submitted to the Timely Communications section (which is unreviewed and hence fast) on topics that are of joint interest to numerical analysts and computer algebraists would be very welcome. We also have a new Formally Reviewed section, for which papers undergo a thorough (but still quick) formal review process. Successful papers receive an imprint on their first pages when published. I invite you to submit papers for this section. Finally, I invite you to join SIGSAM. Membership benefits include receiving the Bulletin, and also a free copy of the proceedings of ISSAC. You may find a membership application form at the back of the last two issues of the Bulletin, or you may join by filling out the registration form at the ACM home page: http://www.acm.org/ As a very last remark, I note that the 1997 ISSAC meeting will be held July 21--23, 1997, in Maui (see the message elsewhere in this NA.Digest). These dates do not conflict with the SIAM 45th annual meeting in Stanford; indeed they suggest a very interesting summer with attendance at SIAM, followed by PASCO (Parallel Symbolic Computation) in Hawaii, ISSAC, and finally Applications of Computer Algebra all to choose among (the nice thing is that one can choose them all---the last three are all at the same place).
