Subject: Announcement of the Netlib Conferences Database
A major reconstruction of the Netlib Conferences Database has just
been completed. The database is now designed to cater exclusively to
the World Wide Web community. It allows anyone with a web browser to
perform keyword searches or simply browse through upcoming conferences
related to mathematics or computer science. In addition, those interested
in announcing conferences to a large audience can submit conferences
to the database with their web browsers.
The database includes conferences that are announced in the
NA-Digest, in Internet news groups, and in many other sources. The WWW
community is also encouraged to submit conferences to the database.
Submitting a conference is quick and easy and allows the submittor to
specify a conference url, if desired. Once a conference has been
submitted, it is easy to update if any of the information changes.
The url for the Netlib Conferences Database is :

Subject: Website for Test Problems
In testing new codes for solving initial value problems for ODEs and
DAEs, it is necessary to have relevant test problems. If every
researcher could refer to one widely used set of test problems and
implement the same Fortran codes, then a lot of time spent on
describing and programming test problems would be saved. Moreover,
if everyone would use the same source, i.e. the same formulation,
parameters, integration interval, initial values, way of programming,
etc., the comparison between the results of several authors would
become much more easy.
For these purposes a test set has been made available on the World Wide
Web at:
http://www.cwi.nl/cwi/projects/IVPtestset.html
In order to let this test set become a success, we kindly request you
to contribute new test problems. However, to restrict the amount of
work for us to incorporate these problems in the test set, it is
important that the submissions are in the prescribed format: Every
problem should have a PostScript file with a description of the problem,
and a set of Fortran routines that are necessary for implementation.
A reference solution has to be included as well.
Detailed information on the format can be found at the WWW page
mentioned above.
Any suggestions, remarks and, most of all, new test problems in the
prescribed format, are welcome.

Subject: New Book, Matrices of Sign-solvable Linear Systems
NEW BOOK ANNOUNCEMENT
We are pleased to announce the publication of the book:
Matrices of Sign-solvable Linear Systems
Richard A. Brualdi and Bryan L. Shader
Cambridge Tracts in Mathematics, No. 116
xii + 298, ISBN 0-521-48296-8
Cambridge University Press.
The list price of the book is $49.95 but it will be offered in Cambridge's
fall catalog at a 20% discount. A description of the book follows.
The sign-solvability of a linear system implies that the signs of the
entries of the solution (or at least some of the entries) are determined
solely on the basis of the signs of the coefficients of the system. That
it might be worthwhile and possible to investigate such linear systems was
recognized by Samuelson in his classic book Foundations of Economic
Analysis. Sign-solvability is part of a larger study which seeks to study
and understand the special circumstances under which an algebraic,
analytic or geometric property of a matrix can be determined from the
combinatorial arrangement of the positive, negative and zero elements of
the matrix. These are thus properties shared by all members of a
qualitative class of matrices. Several classes of matrices arise in this
way, notably sign-nonsingular matrices, L-matrices, S-matrices, and
sign-stable matrices. The essential idea of a sign-nonsingular matrix
arose in a different context in the key 1963 paper Dimer statistics and
place transitions by P.W. Kastelyn. The large and diffuse body of
literature connected with sign-solvability is presented as a coherent
whole for the first time in this book. Results in the literature are
presented in a new and organized way with many new connections established
and with many new results and proofs. One of the features of this book is
that algorithms that are implicit in many of the proofs have been
explicitly described and their complexity has been commented on.
The book is intended primarily for researchers in combinatorics and linear
algebra but it should be of interest to theoretical computer scientists,
economists, physicists, chemists, engineers and other scientists. It
should also be of interest to those who would like to see the beautiful
interplay that it affords between combinatorics (especially, graph theory)
and linear algebra.
The book is self-contained but it does assume that the reader is familiar
with elementary linear algebra and has been introduced to some aspects of
graph theory and combinatorial matrix theory.

Subject: Eigenvalue Problems and Applications
During the past few years a few of my colleagues and I have been
exploring algorithms for the solution of the partial eigenvalue problem.
We have solved large problems (matrices of order up to 64,000) using
various methods and would like to identify the current major application
areas which require the solution (partial or otherwise) of large
eigenproblems. For each application identified we are also interested in
the maximum order of problem encountered and the number of eigenvalues
required. In those cases where only a few eigenvalues are required it
would also be helpful to know which ones are needed (the largest, the
second largest, etc.).
Any information on the above would be greatly appreciated.

Subject: Report on the Dendee Conference
Report on the 16th Biennial Conference on Numerical Analysis
The 16th Biennial Conference on Numerical Analysis was held at the
University of Dundee, Scotland, Tuesday 27 June - Friday 30 June, 1995.
Except for the first meeting hosted by St. Andrews University in 1965,
the meeting has been held on the campus of the University of Dundee.
This is the numerical analysis conference "not to miss"
in Britain and thus attracts a sizeable international crowd. This report
is a brief summary of the conference. Further information, including
abstracts of all talks, both contributed and invited, is available
on the conference Web page, with
URL: http://www.mcs.dundee.ac.uk:8080/~dfg/95conf/contents.html.
Beside the conference itself, the lasting impression of the conference
was the stunning weather. Sun soaked and warm days were followed by cool
nights. Add the scenic River Tay and the Scottish countryside and the
picture perfect setting was made to order. The conference was preceded by a
one day meeting on Monday June 26 at which talks were given by those
short-listed for the Leslie Fox Prize. In honor of the late Professor Leslie
Fox, the award is given to a young researcher based upon a paper submitted
early in the year to the judging committee as well as a forty minute talk.
The judges for this event were:
Professor Charlie Elliot (University of Sussex), Professor Christopher Baker
(University of Manchester) and Professor Iain Duff (Rutherford Appleton
Laboratory). Adrian Hill of the University of Bath was awarded the prize for
his research on global dissipativity for A-stable methods.
The conference was opened by remarks from Professor Roger Fletcher and then
the three and half days comprising fourteen invited lectures and well over
one hundred contributed talks, in two or three parallel sessions, were underway.
The first talk was the A.R. Mitchell Lecture given by Professor K.W. (Bill)
Morton (University of Oxford) on Finite volume methods. The lecture is in honor
and recognition of Professor (Emeritus) Ron Mitchell's contribution to numerical
analysis at Dundee and throughout the world. Professor Gene H. Golub (Stanford
University) followed with the second invited lecture on Inner/Outer iterations
for solving linear systems of equations. The third invited talk was given by
Dr. Margaret H. Wright (ATT Bell Labs) entitled "Direct search methods: once
scorned, now respectable". Professor Robert D. Russell (Simon Fraser University)
followed lunch with the fourth invited lecture of the day on "Moving mesh
methods, with applications to blow-up problems for PDEs." The final invited
lecture of the day was given by Dr David Silvester (UMIST) on the subject of
fast & robust solvers for time-discretised incompressible Navier-Stokes equations.
Wednesday was started by Professor Will Light (University of Leicester) who gave
an invited lecture on "Variational error bounds for radial basis functions."
Professor Beresford Parlett (University of California at Berkeley) gave the
second invited lecture on the subject of computing orthogonal eigenvectors
without the Gram-Schmidt algorithm. Following a break for lunch, Professor
Andreas Griewank (Technical University of Dresden), gave an invited lecture on
solving ordinary differential equations with automatic differentiation and
rational prediction. Professor Jochem Zowe (University of Bayreuth) gave the final
invited lecture of the day on non-smooth methods and their role in the
optimization of mechanical structures. The night was capped off by a brilliant
football (soccer) match between Scotland and the rest of the world. Home advantage
proved crucial as Scotland prevailed with four goals to the other team's one.
Professor Linda Petzold (University of Minnesota) gave the first invited
lecture of the Thursday. She discussed the computational challenges involved
in the solution of nonlinear multi-body dynamics systems. Professor J. M.
(Chus) Sanz-Serna (University of Valladolid) gave the second invited talk of
the day on "Efficient pre- and post-processing of symplectic integrations."
Professor Rolf Jeltsch of the (Federal Institute of Technology, Switzerland)
then gave the invited talk after lunch on "Multidimensional schemes for
nonlinear systems of hyperbolic conservation laws." The final invited talk of
the day, given by Dr Andre S{\"u}li (University of Oxford), considered the role
of a-posteriori error analysis and global error control for use in adaptive finite
volume approximations for hyperbolic problems. On the Thursday night, attendees
met at Bonar Hall where Professor John Butcher (University of Auckland) gave a
memorable speech on Runge-Kutta methods after an excellent dinner.
The final day saw Dr. David Griffiths (University of Dundee) give the last
invited talk on discretised eigenvalue problems, LBB constants and
stabilization.
Thanks are due to the organizing committee of David Griffiths, Des Higham and
Alistair Watson of the University of Dundee for a most enjoyable conference.
The informality of the meeting allowed the attendees to spend much time in
conversation with new and old colleagues. Rarely does a major meeting provide
the opportunity to learn about so many areas of numerical analysis.
The author is gratefully acknowledges Des Higham for his constructive remarks
that improved the quality of the initial version of this report.

STANFORD UNIVERSITY FORSYTHE FELLOW
Scientific Computing and Computational Mathematics Program
2 Year Assistant Professorship
Dynamical Systems and Numerical Analysis
Start Date: 1st January 1996
The School of Engineering at Stanford University has
established Forsythe Fellows in the Scientific
Computing and Computational Mathematics (SCCM) Program.
These positions have a duration of two years and are
jointly funded through the School of Engineering and the
research support of faculty members in the SCCM Program.
An optional third year of funding may be available, contingent
upon financial resources.
Research
This particular fellowship will be associated with
Professor Andrew Stuart of the Departments of Computer
Science and Mechanical Engineering. The broad area
of research is in dynamical systems and numerical
analysis. Commonly used software for the solution of
initial-value problems may be formulated as a discontinuous
dynamical system for the evolution of the approximate solution
and the time-step. The objective of the research is to
study the relationship between this dynamical system and
that generated by the underlying differential equation.
Applicants are sought who have demonstrated expertise
and interest in application of the theory of dynamical systems
to the analysis of numerical methods for initial value problems;
in particular, candidates with knowledge of the theory of
discontinuous dynamical systems are encouraged to apply.
Teaching
The Forsythe Fellow will be expected to be involved in
the SCCM program which is an interdisciplinary graduate program
awarding MS and PhD degrees. He/she will teach two courses
within the SCCM program each academic year and will also
help in the administration of the weekly SCCM seminar.
Typically one of these courses may be at an advanced level and
in the field of interest of the Forsythe Fellow whilst
the other will be an undergraduate, or beginning graduate, level
course in computational mathematics or numerical analysis.
