Subject: Henk van der Vorst Knight in the Order of the Dutch Lion

On Saturday July 22, Henk van der Vorst was awarded the royal
distinction called "Ridder in de Orde van de Nederlandse Leeuw",
which stands for "Knight in the Order of the Dutch Lion".

The ceremony took place at the end of a one-day minisymposium
in honor of Henk's early retirement:

http://staff.science.uva.nl/~brandts/HENKvdVORST/

The distinction is given to people who have contributed to society
in a very special manner. It refers to exceptional personal
achievements, to efforts of unusual nature, or outings of special
talents. In particular, it is about pure individual class which
also had its impact on society. For example, the well-known Dutch
two-fold gold Olympic medalist 100 m freestyle swimming Pieter van
den Hoogeband shares the same distinction.

We congratulate Henk with this very special, well-deserved honor!

Subject: Numerical calculation of eigensystems for very small matrices

I am looking for an efficient algorithm to calculate the eigensystem of
a large number of very small (3x3) hermitian matrices. Standard methods
turn out to be relatively slow, so I came up with the following method:

Let A be a hermitian 3x3 matrix.
1. Find the first eigenvalue lambda_1 using a Steffenson algorithm.
2. Calculate the eigenvector v_1 as the cross product of two columns of
the matrix (A - lambda_1*I), to which v_1 must be orthogonal. Here, "I"
denotes the 3x3 unit matrix.
3. Use a Householder transform to bring A to the form
/ * \
| * * |
\ * * /
4. Solve the remaining 2x2-problem directly.

Of course, there are several special cases which require a separate
treatment, e.g. if the columns of (A - lambda_1*I) are almost linearly
dependent.

For my purpose (simulation of processes in elementary particle physics)
this method is reasonably fast, and also the accuracy is sufficient.

I would appreciate to hear your opinion on the above algorithm, and on
possible other numerical solutions to small scale hermitian eigenproblems.

Subject: Coleridge's report on the SIAM Annual Meeting

Although incognito, Coleridge was also present at
the SIAM Annual Meeting, held in Boston a little
over a week ago. Below is his report on the meeting:

In Boston Mass did SIAM hath
a lively conference, week past.
Where endless urns of coffee ran;
Tenser products measureless to math,
From one to speaker last.

When he asked me to post his report, I attempted
to correct his spelling of "Tenser" but he insisted
it was correct in this context.

Subject: WDSTFFS 2006, an International Workshop, Sep 1-4, 2006

International Workshop on Wave Dynamics and Stability of Thin Film Flow
Systems WDSTFFS September 1 – 4, 2006

A four Day international workshop on Wave Dynamics and Stability of
Thin Film Flow Systems is being organized by the Department of
Mathematics, IIT Madras, Chennai. A range of topics is covered in the
workshop and leading experts in this field are coming together to
deliberate advancements, scope and applications of Thin Film Flow Systems.
Organizers of this four day workshop cordially invite all those interested
to participate in the workshop.

WDSTFFS – 2006 is a premier international workshop in India in the
area of thin liquid films, related process fundamentals and applications.
The scope of the workshop is to provide a forum for discussion of recent
developments and future directions of the understanding of Thin Film Flow
Systems, their stability characteristics and applications. The workshop
will highlight on the underlying intricate mechanisms, the necessity for
accurate modeling of a variety of dynamic phenomena exhibited by Thin
Films with an emphasis on the novel applications, current challenges and
opportunities.

The main aim of the workshop is to bring together leading experts and
researchers working on different problems like surface instabilities of
heated or falling film, inertia effects in falling liquid films, influence
of surface tension gradients, vapor liquid interface dynamics in film
boiling, instability and transport phenomena in thin liquid films,
dynamics, stability and pattern formation in surfactant-driven thin film
flows, film blowing of polymers, the influence of chemical reactions,
Marangoni instability of a binary-liquid film with soret effect or human
tear film dynamics.The contributions will report both fundamental and
applied research and will cover the range from experimental and
theoretical work to applications from engineering to biology. It is the
intent of the workshop to provide networking platform for interaction with
delegates from a diverse set of backgrounds and promote global exchange of
information among scientists and technologists.
