Report on Midwest NA Day
Paul Saylor and Ryan Szypowski
(with thanks to Tim Trick)

Midwest NA Day was held Saturday, May 12, 2001 at the University of
Illinois, Urbana-Champaign (UIUC), with approximately sixty attendees.
Speakers were here from various Midwestern Universities. Also present were
participants from outside the Midwest, in particular, Bill Gear from NEC
Research (retired), Gene Golub from Stanford, and Zdenek Strakos from the
Czech Academy of Science. Topics ranged over stiff odes, Toeplitz systems,
unimodular polynomials, Krylov methods, the Wilkinson polynomial,
continued fractions, fill-in prediction, fluid mechanics and the method of

The weekend of May 12-13 was graduation weekend at UIUC, normally a weekend
to avoid, due to an influx of visitors seizing all the hotel rooms,
restaurants and parking places. But a special event justified this date.

Bill Gear received an Alumni Achievement Award, bestowed at graduation
ceremonies on Sunday, May 13. His portrait now hangs in a corridor of the
UIUC student union, one might say in the Alumni Hall of Fame.

There are many other distinguished recipients of the Alumni Achievement
Award whose portraits are also on display. Among them:

Arnold Beckman Sydney Drell
Jim Brady Jack Kilby
James Reston Robert Schrieffer
David Blackwell Rosalyn Yalow

More on Bill's achievements in stiff methods. A good example to show the
influence of his work is electronic circuit simulation where eigenvalues
can vary over six orders of magnitude, the cause of stiff instability.
(Some liberties are taken in the name of simplicity.) These instabilities
had been known about for a long time before Bill's contributions, with a
commercial circuits code appearing in the early sixties that used the
backward Euler method to deal with stiffness. Then, when Bill's work
appeared, electronic circuits engineers adopted his A-stable methods with

One noteworthy activity typified the ferment of the times. In an intense
ten year period peakng in the mid-seventies, UC Berkeley engineers
developed their important Simulation Program with Integrated Circuit
Emphasis (SPICE), which made use of Bill's stiffly stable methods. The
rapid spreading of this give-away package assured the wide distribution of
any novel method to be found inside, including Bill's.

Simulation is a tool in the design of circuits such as those inside
internet operations and telecommunication equipment. (What we've got here
is not a failure to communicate.) The proliferation of circuits and the
influence of the underlying design algorithms therefore being everywhere,
means that, in the world of ubiquitous computing, Bill's algorithms are
ubiquitously computing.

Subject: Applied Math/Numerical Analysis Job Listings on the Internet

Several weeks ago I posted the following request on na-net:

Does anyone have recommendations for internet sites that have job
listings for graduating students who are looking for work related to
numerical analysis or applied mathematics? Sites that include listings
for students with bachelors and masters degrees are of interest.

Here is a summary of the replies that I received.

General technical-related sites:,,,,,, and

in the UK:,, GoJobsite also has sites in
France, Germany, Ireland, Italy, and Spain.

in Ireland:

in Germany:,,,,

GSCI-digest regularly lists jobs opportunities for beginners in
numerical analysis and scientific computing : A related site is

computational fluid dynamics:

operations research/management science: and

Applied math, math and scientific computing jobs (mostly for academic

computational mathematics: and

Many of the above sites have useful links. Some sites allow you to
store your resume. Employers can (and do!) search these to directly
contact applicants

Andy Cleary (Data Digest Corporation) gives some great advice for job

'For industry jobs, in my experience the best bet is to go to some of
the major computing-related job posting sites and to get creative with
your search criteria.,,,,, are probably the 5 I've used the most.
None of them will focus on numerical analysis or mathematics in general:
in the big bad business world, we have to accept that mathematics is a
fairly minor niche. Nonetheless, there are jobs out there that involve
mathematics. When filling out resumes for these sites, it is important
to be exhaustive about computing abilities and technologies, because
just about every math related job out there will be computing or
software first, math second. When performing searches, some of the
keywords that I have found useful are analysis/analytical, algorithms,
math (obviously), computation... Honestly, I haven't seen many hits for
"numerical analysis", but it's always worth a shot...'

'Before the recent slump in Nasdaq and the hightech market, there were a
LOT of industry jobs for people with this kind of background ... I
expect this to pick back up very shortly. ... Innovative work is being
done these days ... in small companies built around new technologies and
for some, this may be a better option both in terms of interesting work
as well as environment and financial reward.'

I received comments from Matthew Saltzman, Ivo Wenneker, Peter
Spellucci, James Blowey, Mei Kobayashi, A. Sazegari, Helmut Roth, Ulrich
Ruede, Steven Ashby, Joerg Gablonsky and Andy Cleary. Thanks for your

Subject: New Book on Acoustic and Electromagnetic Equations

J.-C. Nedelec "Acoustic and Electromagnetic equations,
Integral representations for harmonic problems",
Applied Mathematical Sciences, Volume 144
Springer-Verlag, 2001, ISBN 0-387-95155-5

This book is devoted to the theoretical study of integral equations
arising in acoustic and electromagnetic problems. The book is organized
as follows :

Chap. 1 : Some Wave Equations
This chapter gives a brief description of the physical equations
discussed in the book.
Chap. 2 : The Helmholtz Equation
This chapter introduces several tools (spherical harmonics, Bessel
functions, elementary differential geometry) used to describe the
solution of Helmholtz equations. It contains a result of existence and
uniqueness for an exterior domain.
Chap. 3 : Integral Representations and Integral Equations
This chapter introduces the essential properties of integral
representations and integral equations in the scalar case (Laplace and
acoustic equations).
Chap. 4 : Singular Integral Operators
This chapter describes the theory of singular integral operators and
gives application to integral equations.
Chap. 5 : Maxwell Equations and Electromagnetic Waves
This chapter gives a complete mathematical treatment of Maxwell
equations, from existence and uniqueness results up to the study of the
associated integral equations. In particular it contains original
results by the author in the dielectric case.

This book is almost self-contained in terms of mathematics and is
accessible to a very broad public ranking from mathematicians to
electrical engineers. In particular it provides with very firm basis for
the numerical treatment of these equations, a field in which the author
of the book is also a world-renowned specialist.

Subject: New Book on Grid Generation

A new book on the numerical treatment of problems whose
solutions have boundary and interior layers has been published by VSP
Publisher: V.D.Liseikin "Layer-Resolving Grids and
Transformations for Singular Perturbation Problems" VSP, Zeist,
2001, ISBN 90-6764-346-7. This book elaborates the topic of layer-resolving
grid generation technology for the numerical solution of problems with
singularities. This theme was given an introductory attention in
the previous monograph by the author: V. D. Liseikin "Grid
Generation Methods", Springer, Berlin, 1999, ISBN 3-540-65686-3.
The present monograph pursues the author`s conviction that a cooperation of
analytical analysis of the qualitative properties of singularities
and computational technology can really boost the efficient
development of the numerical codes aimed at the solution of problems
with singularities.

The book is largely devoted to a qualitative study of
various types of boundary and interior layers and to a detailed
review of those important aspects concerned with the development
of the numerical techniques based on updated, comprehensive
layer-resolving grids for equations with singularities which have
not been covered in the written monographs. Special attention is paid to
the qualitative analysis and generation of the layer-resolving grids
for nonlinear and the so-called problems with boundary and interior turning
points which have additional singularities from the reduced
problems. These problems are the most important for applications
and the most difficult for the pure analytical and numerical studies.

Subject: PhD Positions at FOM Rijnhuizen, Netherlands

2 PhD Positions in Numerical Plasma Dynamics

The FOM Institute for Plasma Physics `Rijnhuizen', the Netherlands, in
particular the Numerical Plasma Dynamics group [1] led by Dr. Rony Keppens
in close collaboration with Prof.Dr. J.P. (Hans) Goedbloed, has an immediate
opening for two PhD students to engage in national and international
research collaborations. The group at Rijnhuizen has extensive expertise
in computational magneto-fluid dynamics applied to laboratory and astrophysical
plasmas. A Netherlands based effort on ``Parallel Computational Magneto-Fluid
Dynamics'' [2] is led by us and we are actively
participating in an international collaboration on
``Plasma Astrophysics: Theory, Observations, and Numerics" [3].

One PhD position is in an international collaboration on
thermonuclear fusion research. She/He will be one of 6 PhD students
currently advertised. The research will focus on how to create
an equilibrium condition in the torus-shaped, magnetized plasma in the
presence of moderate to significant background rotation. Specifically, she/he
will investigate the modifications of the magnetohydrodynamic waves
and instabilities for the experimental TEXTOR tokamak configuration.
The PhD student will address such intriguing questions as:
(1) how does flow modify the equilibrium properties?
(2) how does flow impact the overall stability of the equilibrium?
(3) what is the influence of spatially varying rotation on the waves?
(4) are there hitherto unknown magnetohydrodynamic wave modes due to the flow?
The possibility of predicting new phenomena will inspire experimental
campaigns in the TEXTOR collaboration, undertaken by other team members.

The second PhD position is in a national research programme addressing
the physics and realisation of a novel, compact plasma accelerator
(FOM programme on ``Laser Wakefield Accelerators'').
She/He will use state-of-the-art computational tools to
analyze the dynamics of plasma channels created by cylindrical
implosions. The simulation results will be used to guide and interpret
the experimental component of the research programme where such imploding
plasma channels will be created. Ultimately, the combined
computational, theoretical, and experimental knowledge should lead to a
scenario for the controlled formation of narrow plasma channels
for guiding laser pulses. The research will focus on the magnetohydrodynamic
stability and evolution of the fully ionized plasma. In a stepwise
approach, the PhD student will unravel the dynamic characteristics of (1)
infinitely long, (2) longitudinally bounded, and (3) fully
three-dimensional plasma columns. This approach will bring unprecedented
insight in the evolution
of capillary discharges, with interacting instabilities, shock formation,
and produced radiation.

Applicants for either position must have an interest in computational and
analytical work related to laboratory or astrophysical plasmas, and be
eager to learn about magnetohydrodynamic modeling. The position is for a
period of 4 years, the location is in Nieuwegein, the Netherlands. More
