Subject: Professor Lothar Collatz

P r o f e s s o r L o t h a r C o l l a t z

On 26 September, Professor Lothar Collatz died at the Black Sea Coast
of Bulgaria, where he attended an international Symposium on Computer Arith-
metic, Scientific Computation, and Mathematical Modelling (SCAN-90). After
a first light heart attack, he suffered a second, fatal heart attack at the
hospital to which he had been taken. The previous two days, he had actively
participated in the meeting, given a paper, and asked the last question
after the last lecture on the day before his death which came as a shock to
all of us present at the conference.

This is not the place to review Professor Collatz's achievements; but
it is clear that the scientific community has lost one of the earliest pio-
neers of Scientific Computation and Numerical Mathematics, and a wonderful
person. At the celebrations of his 80th birthday on 6 and 7 July this year
in Hamburg, the numerous speakers wished him many more prolific and enjoy-
able years to come. These wishes have not come true; but he will remain
alive in our memories, and his ideas will continue to stimulate our work.
May he rest in peace.

Subject: Happy Birthday, Pete

Monday, October 1 was the 50th birthday of G. W. "Pete" Stewart. Pete
has contributed enormously to our field through his research in
perturbation theory and numerical algorithms. Beyond his elegant work,
he is a man of style and wit. In my head, Pete is a successor of his
adviser, Alston Householder, and of Jim Wilkinson.

A recent accomplishment of Pete's is his book with Ji-guang Sun,
"Matrix Perturbation Theory", Academic Press. It is a pleasure to
read; it is in the clear and concise style of all of Pete's writings.

So three cheers for Pete. Here's for many more years of productive research;
I'm sure they'll be golden ones.

Subject: A Colleague from Kuwait

Dear Colleagues:

Last Thursday I received an unexpected, but very welcome telephone
call from Fuad Kittaneh, a colleague who until August 2 was Associate
Professor of Mathematics at Kuwait University. Fuad and I have corresponded
for a long time by mail, and this last year we collaborated (with Rajendra
Bhatia) on a paper that will appear in the forthcoming special issue of
Linear Algebra Appl. on canonical forms.

Fuad and his wife have four children, two of whom are U.S. citizens.
That may be why the U.S. embassy in Kuwait was able to get them all on one
of the refugee flights that arrived last week in Raleigh, N.C. Although
they are now safe from harm, they have lost everything and need to restart
their lives in the U.S. Fuad recognizes that it may take some time and
luck to find a permanent job, but he is willing now to do anything, anywhere
that will give him an office, phone, library, some income, and a base of
operation from which he can conduct a search for a permanent job.

Do you know of anything that might help Fuad? An unexpected
faculty vacancy due to illness or resignation? A graduate T.A. slot that
is vacant because someone didn't show up or left in mid-year? Some left-
over research support funds in a grant that doesn't require U.S. citizen-
ship? Funds available to pay part-time teaching staff?

I have a copy of his C.V. and graduate transcript, and will be
happy to send a copy to anyone who needs it. He did his Ph.D. at Indiana
University under J.G. Stampfli in 1982; his thesis was in functional
analysis/operator theory and that has been the main theme of his research
work during the last 10 years. He has published 30 papers and has
7 more under submission right now. He has taught a wide variety of
courses--most everything in the usual mathematics undergraduate curriculum.
His English is quite fluent, but accented. He was born in 1955 and holds
Jordanian citizenship.

Please feel free to copy this message to anyone else.

For more information, or if you have any leads you would like me
to pass on to Fuad, please contact me at RHORN@JHUVMS, or phone me at
301/338-7998 (JHU) or 301/561-0579 (home).

Thanks, Roger Horn

Subject: Recommendations Sought for ODE Codes

I would like some recommendations for available software packages
(source code) for the determination of solutions to coupled nonlinear
autonomous ODE's. Relative ease of use is important for this initial
investigation. Presently the existence of multiple stable or unstable
solution branches is unknown. A reasonable initial guess is available.
I would prefer if some type of reasonable graphical output was available.
The ideal platform would be some type of workstation such as a sun4.
Thank you for any helpful recomendations.

Subject: Applied and Industrial Mathematics

Here are the abstracts of the five articles "of numerical interest" in
the KLUWER volume "Applied and Industrial Mathematics. Venice-1,1989",ed.
by R.Spigler,to appear in November 1990.
1. "The Hamiltonian way for computing Hamiltonian dynamics",by Feng
We present a survey of a recent comprehensive study on the numerical
methods for Hamiltonian systems based on symplectic geometry,together
with the motivations for the research,justification for the symplectic
approach adopted,some of the main results,their ramifications and their
2. "The speed of waveform methods for ODEs",by C.W.Gear and Fen-Lien
This paper considers iterative solution techniques for ordinary
differential equations and investigates the speed of convergence of
various processes. The iterates are defined as solutions of a sequence
of differential equations. The solutions are the "waveforms". Waveform
iterations are superlinearly convergent so a measure of the speed of
convergence is defined and this is used to compare the value of various
waveform methods. This measure is the rate of increase of the order of
accuracy. The speed of the waveform Gauss Seidel method depends on the
numbering of the directed graph specifying equation dependencies. We
show how to compute the rate of order increase from the structure of the
numbered graph and hence the optimum numbering,that is,the one which
maximizes the speed of convergence.
3. "Computational methods for the Boltzmann equation",by
F.Gropengiesser,H.Neunzert,and J.Struckmeier.
This paper contains the basic ideas and practical aspects for numerical
methods for solving the Boltzmann equation. The main field of
application considered is the reentry of a apace shuttle in the
transition from free molecular flow to continuum flow. The method used
will be called Finite Pointset Method,approximating the solution by
finite sets of particles in a rigorously defined way. Convergence
results are cited while practical aspects of the algorithm are
emphasized. Ideas for the transition to theNavier-Stokes domain are
shortly discussed.
4. "Theory and application of Steklov-Poincare' operators for
boundary-value problems",by A.Quarteroni and A.Valli.
This paper deals with interface operators in boundary-value problems.
How to define them,which is their meaning in both mathematical and
physical sense,how to use them to derive numerical approximations based
on domain decomposition approaches.
5. "Numerical analysis for compressible viscous isothermal stationary
flows",by C.BernardiM.O.Bristeau,O.Pironneau,and M.G.Vallet.
In this paper we address the problem of approximation of viscous
compressible flows by the finite element method. Should one use the same
approximation for the density and the velocity as in Euler flows,or
should one use two different spaces as for the Stokes problem ? When the
pressure is a function of the density (isothermal flow as an academic
example),we show theoretically and numerically convergence of the
approximations if the density and the velocity are approximated as in
the Stokes problem,with two different grids or if artificial viscosity
is used in the equation of conservation of mass.

FORTRAN - SC is a programming language for scientific/engineering
computation on IBM s/370 architecture machines. It is particularly
suited for the development of numerical algorithms delivering
highly accurate and automatically verified results. It includes an
extensive library to support interval arithmetic. I used a
predicessor to write a package for numerical quadrature with
guaranteed bounds. The new product is more extensive, easier to
use, and better documented. You might want to contact your IBM
salesperson for more details. I have not seen a price list, but I
understand that it is inexpensive, at least for universities.

A R Mitchell Fund

The 1991 Dundee Numerical Analysis Conference will celebrate
the 70th birthday of A R Mitchell. In addition to his
distinguished contributions to numerical analysis extending
over many years, Ron has been known for the outstanding
encouragement he has given to young numerical analysts and
the Organizing Committee therefore felt it appropriate to
mark his birthday by instituting a special fund to provide
assistance to young numerical analysts to attend this and
subsequent Dundee meetings.

We extend an invitation to all numerical analysts to
contribute to this fund and cheques should be made payable
to "The University of Dundee: A R Mitchell Fund". It is not
intended that there should be any formal means of applying
for support from the fund but the organisers welcome
enquiries from anyone who feels that they may be eligible.
Allocation of funds will be made on the basis of need, and
also on the basis of abstracts of papers intended for
presentation at the conference.
