**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

previous ones.

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now out of date.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.

Anonymous FTP at the University of Greenwich:

We have recently fixed our ftp facility. Therefore it is possible for you to

obtain nma series by anonymous ftp to maths.gre.ac.uk and the nma series are

recorded as .dvi files under the directory pub/nma. A readme file in pub/nma

gives a brief description. This readme file will be updated from time to time

as more reports are included into the series.

A large number of people response to my previous message regarding the

report nma001. I have sent off the tex file via email to some of the people

before the ftp was fixed. Hardcopies were sent off to those who have

specifically asked for. I apologise for not sending hardcopy to everyone.

**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)

Abstract:

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

nonlinear problems.
