Subject: SIAM Conferences
I recently attended the Third SIAM Conference on Linear Algebra Signals,
Systems and Control in Seattle. Several persons made comments to me which I
think should be discussed publicly. Perhaps in light of these comments, it is
necessary to re-think the SIAM policy on conferences. Other
organizations, please note.
Here are some of those comments.
1) There are too many parallel sessions with too few attendees.
2) Talks were rehashs of talks given in the previous two years.
3) At least one session was dedicated to a commercial product: Matlab.
4) The meeting began too early in the morning, 8am.
5) This conference was organized by the same person who organized the
6) Many talks had little to do with the main theme of the meeting.
Perhaps the policy of accepting all abstracts and parallel sessions is
now out of date.
If you wish to make your comments known to the SIAM leadership, send a
message to na.siam.

Subject: How to Discriminate Between Typing Mistakes and Intentional Ones?
Problem: a numeric code of about 11 digits must be specified in certain
documents; some of the digits depends on the others, so it is
possible to detect any mistake; since it is possible to extract a
sample of the incorrect documents and perform a manual search to
determine the correct codes, now the problem is to discriminate
between typing mistakes and intentionally deceptive mistakes.
Question: what is needed is a routine/algorithm/method, possibly certified
or previously used in significant cases (or at least some pointer
to the right place where to ask), aimed to discriminate between
small errors - probably due to typing mistakes - and other kind of
changes, subject to be investigated as deceptive actions.
Thank you in advance.

Subject: Query on Convergence of Infinite Products of Matrices
We (Walter Van Assche and Paul Nevai) are interested in the convergence of
the infinite product $\prod (I+A_n)$ where $I$ is the identity matrix and
$A_n$'s are square matrices (of fixed finite order). We know that the
infinite sums $\sum A_n$ (conditionally, elementwise) and $\sum ||A_n||^2$
(the square of the norms) converge. The matrices $A_n$ do not commute with
each other. Under what (additional, if any) conditions can we conclude that
$\prod A_n$ converges? Can you give me some references or suggestions who I
should contact on such matters? Thanks...Paul Nevai
P.S. We would be interested even in the case when the matrices are $2x2$
and the diagonal elements are always zero.

Subject: Nonlinear Elliptic PDE and Picard Iteration
We are trying to solve nonlinear elliptic equations of the form:
Uxx + Uyy = f(U,x,y)
Where f is nonlinear function of U. We need to solve for U(X,Y) in rectangular
region and the boundary are of mixed type.
We wish to solve this problem using point iteration method , known
also as Picard Method. That is assume U = U(k-1) on the right side of Eq.1
during the k th iteration, until U(k) = U(K-1). So iterate the
following linear equation until convergence:
Uxx(k) + Uyy(k) = f(U(k-1),x,y)
OUR question is there any way we can improve the accuracy and
convergence of the point iteration method. We are obtaining results that
are ok but!, but not as accurate as Newton Method ...
Any advises and suggestions (or where should we look) are appreciated.

Subject: New Book on Parallel Multigrid Waveform Relaxation
I would like to announce the publication of the book:
"Parallel Multigrid Waveform Relaxation for Parabolic Problems"
by Stefan Vandewalle, in the series Teubner-Skripten zur Numerik,
B.G. Teubner Stuttgart, Germany, 1993.
(16.2 x 23.5 cm, 247 pages, DM 39.80, ISBN 3-519-02717-8)
Waveform relaxation is a highly parallel iterative method for
solving very large systems of ordinary differential equations.
Over the years this method has been applied almost exclusively
for the systems that model VLSI electronic circuits.
In the present work the author studies waveform relaxation
methods for parabolic partial differential equations of initial
boundary-value and time-periodic type. It is shown both theoretically
and by numerical experimentation that waveform relaxation, when
accelerated by using multigrid, is a highly effective algorithm.
It combines a low serial complexity with a high parallel efficiency
and it is easily vectorisable.
The book starts with an introductory overview of the waveform relaxation
theory and practice, and provides an in-depth analysis of multigrid
waveform relaxation. It discusses the parallel implementation of
classical time-stepping schemes and analyses the computational
complexity of waveform relaxation methods. A large number of case-
studies illustrate the performance of the methods for linear and
