Subject: SIAM Activity Group on Linear Algebra Prize

It is a great pleasure to announce the winners of
the SIAG LA prize and the poster prizes awarded at
the Sixth SIAM Conference on Applied Linear Algebra.
The conference took place on October 9 through November 1
in Snowbird, Utah.

The SIAG LA prize is awarded every third year (starting in 1988) at the
triennial SIAM Conference on Applied Linear Algebra, the only all SIAG/LA
meeting. The award period is the three calendar years preceding the meeting.
Further details on the prize may be found on .

This year we have two SIAG LA prize winners!:
1) Ming Gu (UCLA) & Stanley Eisenstat (Yale University) for their paper
"A Divide-and-Conquer Algorithm for the Symmetric Tridiagonal


2) Gerard Sleijpen and Henk Van Der Vorst (Math Institute at
the University of Utrecht) for their paper
"A Jacobi-Davidson Iteration Method for Linear Eigenvalue

An honorable mention was given for "A Formula for Computation
of the Real Stability Radius" by L. Qui (Hong Kong University
of Science), B. Bernhardsson and A. Rantzer (Lund, Sweden),
E.J. Davison (U. Toronto), P. M. Young (MIT), and J. C.
Doyle (Caltech)

We also had many nice posters at this conference.
The following two were selected for a special recognition
as winners of the poster competition.

Subject: Request for Historical Information

I am writing up some lecture notes for an introductory numerical methods
or analysis course, and would like to spice them up by the inclusion of
some historical notes. Getting biographical information on the classic
mathematicians is not difficult, of course, and I have Goldstine's book
on the history of numerical analysis, as well as several other history
of math texts.

What I would like to have are (some pointers to) sources on more modern
people such as Aitken and Richardson, as well as sources on the modern
development of numerical analysis in this century. If anyone has
suggestions, I would be most grateful. Journal articles, pointers to
web sites, or even personal knowledge would be appreciated.

Subject: Iterative vs. Direct Methods

With regard to solving nonsingular linear systems (large and sparse, I
believe), I recently heard a claim that iterative methods are less accurate
than direct methods when the coefficient matrix is ill-conditioned. Does
anyone know of any studies or papers on this, or whether or not this claim
is true?

Subject: A Run-time Parallelization System for Irregular Computations

We have made the first version of the RAPID tool (RAPID 1.0) available
on-line. RAPID is a run-time library system for parallelizing irregular
codes using graph scheduling and fast communication support. RAPID has been
used to parallelize several irregular codes including sparse matrix
computations and n-body simulation. In particular, it helps us to parallelize
sparse Gaussian Elimination with partial pivoting on distributed memory
machines. This release is for Cray-T3E. The package and related papers
can be obtained at the RAPID homepage:

As editor, I am pleased to announce the launch of the new journal-

International Journal of Mathematical Algorithms (IJMA)

IJMA will be concerned with research in the interface of computer science
and mathematics. In particular, the journal will focus on applicable
mathematics such as operational research, discrete mathematics, number
theory and logic where the research reported contains a significant
computing science component. Published papers will have a strong
mathematical foundation and will be concerned with the exploitation of
recent advances in computing generally with a view to solving problems of a
practical nature.

This journal is committed to minimising the delay between submission and
publication of successful papers. The journal has the policy that it will
inform authors of acceptance/rejection within six months of submission.

I would now like to invite authors to submit papers for publication in the
journal. It is foreseen that the first issue will be in early 98. Please
submit manuscripts (3 copies please) to me at the address below, or in the
case of North American workers to Teodor Crainic in Montreal.
Final details of presentation of manuscripts will be sent to authors
following acceptance.

It is hoped that there will also be some special issues - maybe a
collection of selected related papers presented at a meeting. If you have
suggestions for an issue of this nature, I will be pleased to hear from

Topics covered in IJMA include:
artificial intelligence
combinatorial optimisation
computational geometry
cryptographic systems
data structures
graph theory and algorithms
mathematical modelling
mathematical programming
parallel and distributed systems

This list is not meant to be an exhaustive list but rather an indication of
the scope of IJMA.

Below are details of the IJMA editorial board. I am confident that this
new journal will have a wide readership. I hope to receive your suggestions
and/or contributions. I would appreciate it if you could circulate this
memo to your colleagues

Subject: SIAM Student Conference and Annual Meeting of SEAS

The annual SIAM-SEAS meeting in Spring 1998 will be held at Florida
State University in Tallahassee in conjunction with a SIAM Student Conference,
like the highly successful First SIAM Student Conference at Clemson in March
1996. The Conference dates will be from March 19 to 21, 1998, beginning at
1:00 p.m. on Thursday, March 19. The Student Conference is intended primarily
for graduate students, although undergraduates are welcome as well.

The conference program will focus on applications of mathematics
in a wide variety of areas, and include presentations from some recent
mathematics graduates working in industry. There will be a select group of
invited student speakers, as well as many opportunities for students
to present contributed papers. SIAM president John Guckenheimer of
Cornell University, Mary Wheeler of the University of Texas at Austin,
and Michael Waterman of the University of Southern California have all
agreed to give plenary addresses. An industrial mathematician is being
sought as a fourth plenary speaker. Michael Waterman's talk on the
afternoon of Friday, March 20, will be followed by a special session
on Mathematical and Molecular Biology, organized by the inter-university
Program in that area. The other special sessions planned so far are one on
Imaging, organized by Dave Wilson (UF) and one on Higher Order Methods for
Multi-Domain Decomposition, organized by Gordon Erlebacher (FSU). Please
contact Chris Hunter if you are interested in organizing some other special

The conference will merge with the annual meeting of SIAM-SEAS on
the afternoon of Friday, March 20. The student emphasis will continue and
papers contributed by students will be given priority in the scheduling. The

"Mathematics as an Industrial Resource", which, like DEIC, was organized
by the European Consortium for Mathematics in Industry (ECMI).
Experience with the earlier network has enabled ECMI to target two
research areas as being of timely industrial relevance and also offering
interesting possibilities for theoretical development. These are
(1) deterministic differential equations of parabolic or mixed types
with applications to glass, steel and polymer manufacture, and to
coating industries and
(2) stochastic differential equations applied to finance, risk,
polymeric microstructures and aerospace technology.

DEIC will be supervised by ECMI's research committee and it will link
centres at Eindhoven, Kaiserslautern, Linz, Milan, Strathclyde and Oxford.
All these centres have expertise in the two strands of the research theme
and the principal objective will be to expand this research base by
appointing six Research Fellows, one in each centre, starting sometime in
1998 and with a duration of up to 3 years. These fellows will be trained in
applied mathematics or numerical analysis but, as with the HCM network,
each fellow will be expected to spend much time collaborating directly with
industry and with other centres, as well as pursuing his/her own research.
Hence preference will be given to applicants who have an aptitude for
finding industrial and commercial problems that are susceptible to
innovative mathematics in either research strand and who will help to
build up the cache of researchers working in this style in Europe.

The Research Fellowships are open to Nationals of a Member State or
Associated State of the European Union who have the equivalent of a
doctoral degree in mathematical science and will be under the age of 35
at the time of appointment. The fellowships may NOT be held in the
country of which the fellow has nationality. Salary is in local currency on
the appropriate local scale and social security, working facilities and travel
allowances will be the responsibility of the host centre, following EC
guidelines and approval by the network.
