Congratulations to Heinz-Otto Kreiss on receiving the
National Academy of Sciences award.

-- Gene Golub

NAS Award in Applied Mathematics and Numerical Analysis -- a prize of
$10,000 awarded every approximately every three years for outstanding
work in applied mathematics and numerical analysis -- goes to Heinz-Otto
Kreiss, professor, department of mathematics, University of California,
Los Angeles. Kreiss was chosen "for his seminal contribution to the
understanding of differential and difference equations and for his many
outstanding contributions to numerical analysis, fluid dynamics, and
meteorology." The award was established by International Business Machines
Corporation and has been presented since 1972.

Subject: Submatrix with Smallest Lowest Singular Value

Given a full rank matrix with m rows r columns (with m >> r). I would like
to find a subset (of size r) of the rows such that the smallest singular
value of the resulting r by r square matrix is minimized. In other words I
want to solve the following optimization problem. Given a full rank matrix
A with m rows, r columns,

minimize over all r sized subsets S of rows of A : (sigma_r of S)

where sigma_r is the smallest singular value of the r by r matrix S.
I am interested in the r by r matrix S that achieves this minimum.
Does anyone know of any references for this problem ?

I have a set of 10 non-linear equations with 10 unknowns, 8 appearing

Subject: Re: Seeking Sparse Cholesky Solvers

Dear NA-Digest readers,

We received 18 replies to our appeal for sparse Cholesky solvers in
NA-Digest 02/02. We would like to thank all of you who responded.

Summarizing, we were pointed to the following packages (in alphabetical order):
- Boeing commercial sparse Cholesky code
inexpensive university licenses available
Domain-Separator Cholesky Package (also for multiprocessors)
Formerly the Harwell Subroutine Library, free for UK academics only.
MUltifrontal Massively Parallel sparse direct Solver.
- Pastix
Parallel Sparse matriX package
- PARDISO (not free,
SParse Object Oriented Linear Equations Solver
- UMFPACK v3.2
for unsymmetric matrices with a "symmetric preference" option
Watson Sparse Matrix Package (Linux Version - Sometime in 2002)
- Yale sparse matrix package
Five people offered their private Cholesky code.

Some people asked about the kind of problem we need the solver for.
The problem is a discretized quadratic eigenvalue problem, which is
described briefly in our paper
We are now developing a different eigenvalue solver in which we need
to do repeated solves with a positive-definite matrix, for which we
want to apply a Cholesky solver. The number of solves depends on the
number of eigenvalues wanted, which makes a comparison difficult. For
a larger number it pays to invest more in the reordering to minimize
fill-in. Since these solves take much of the time we are willing to
do some comparisons to find some compromise. However, we do not have
sufficient wo/manpower to test all of the packages mentioned.

Subject: New Book in French on Finite Elements

Dear colleagues,

We have the pleasure to announce the release of our new book

Elements finis : theorie, applications, mise en oeuvre
Alexandre Ern and Jean-Luc Guermond
Series Mathematiques & Applications, vol. 36
Springer Verlag, Berlin, 2002
ISBN 3-540-42615-9, 430 p.


These lecture notes present a mathematical theory of finite elements
which emphasizes inf-sup conditions rather than the standard Lax-Milgram
paradigm. Recent developments such as least-squares methods, subgrid
viscosity and a posteriori error control are treated. Each theoretical
topic is illustrated by engineering applications. Practical
implementation aspects (mesh generation, data structure, linear algebra)
are also covered.

Table of Contents

1. Introduction
2. Interpolation par elements finis
3. Problemes bien poses
4. Problemes coercifs
5. Problemes mixtes
6. Problemes du premier ordre
7. Problemes d'evolution en temps
8. Maillages
9. Quadratures numeriques, assemblage et stockage
10. Algebre lineaire
11. Estimation d'erreur a posteriori
A. Conventions de notation
B. Espaces de Banach et de Hilbert

University of Split

In cooperation with SIAM Activity Group on Linear Algebra (SIAG/LA).

Jesse Barlow, The Pennsylvania State University,
Ivan Slapnicar, University of Split, (local manager),
Kresimir Veselic, Fernuniversitaet Hagen, Germany.

The purpose of this workshop is to bring together experts on accuracy
issues in the numerical solution of eigenvalue problems for four days
of research presentations and discussions. This is the fourth such
workshop. The first, titled "International Workshop on Accurate
Eigensolving and Applications", was held at the University of Split on
July 11-17, 1996, the second, "International Workshop on Accurate
Solution of Eigenvalue Problems", was held at the Pennsylvania State
University on July 20-23, 1998, and the "III International Workshop on
Accurate Solution of Eigenvalue Problems", was held at the
Fernuniversitaet Hagen on July 3-6, 2000. The reports on these
workshops written by Beresford Parlett were published in SIAM News
(February 2001, March 1999, October 1996).

The workshop will have similar format as its predecessors: there will
be no parallel sessions; research presentations will be 30 to 40
minutes each, with sufficient time for discussions. Specially titled
discussion/working groups and a poster session will also be organized.

The list of tentative invited speakers includes:

Chris Beattie, Virginia Tech, Blacksburg,
James Demmel, University of California at Berkeley,

Dear colleague:

The Centro Internacional de Matematica (
and the Centro de Fisica Computacional ( are organizing
a workshop on Molecular Geometry Optimization. It will take place in Coimbra,
at the Physics Department of the University, between July 1 and July 3, 2002.
This workshop is intended to bring together mathematicians, chemists and
physicists who work in molecular geometry optimization. Its main goal
is, therefore, to allow the interchange of ideas between scientists with
very different backgrounds and to provide a basepoint for the
development of joint research projects. The use of high-performance
computing software and hardware for performing realistic calculations of
molecular structure will also be highlighted.

Subject: PhD Position at Paul Scherrer Institute

PhD position in numerical reactor physics at PSI (Switzerland)

Applications are invited for a PhD position in numerical reactor physics at
the Paul Scherrer Institute (PSI) in Switzerland.

In the Laboratory for Reactor Physics and Systems Behaviour, the PhD
candidate will work on the development of a numerical methodology for
decomposition of space- and neutron energy-wise contributions to reactivity
effect discrepancies.

Keyword for this project are: nuclear reactor analysis, eigenvalue problems,
generalized perturbation theory, uncertainty propagation modelling

The accurate prediction of reactivity (effective neutron multiplication
factor) in nuclear power plants is of utmost importance from various
viewpoints, including design, economics and operational safety. The proposed
research aims at establishing a theoretical/numerical procedure for
obtaining a systematic breakdown of integral reactivity effects into
individual space- and energywise components at the fuel assembly level. This
will enable the quantification of the relative importance of variations in
different relevant quantities that contribute to a given reactivity effect
of significance to current light water reactor (LWR) technology. Effects to
be investigated at the fuel assembly level are homogeneous changes, like
temperature, coolant density or boron concentration, and heterogeneous,
highly-localised system variations, such as the replacement of a fuel rod by
coolant or the local increase of void.

This work is to be conducted in the framework of the LWR-PROTEUS
( project at the Paul Scherrer Institute (PSI) in
Switzerland, and should result in an EPFL dissertation (Ecole Polytechnique
Federal de Lausanne). The candidate should preferably be a physics or
engineering graduate with a strong interest in nuclear reactor physics and
numerical methods. A good knowledge of English is expected.
