Subject: Ralph Willoughby

Dear Everybody:

I have just learned that Ralph Willoughby passed away
in July of this year. Many of you were touched by
Ralph at some point in your professional career and
remember him as not only someone who possessed a great
love for numerical linear algebra (especially sparse
matrices), but also as someone who practiced his deep
concern for other people, on both a personal and on a
professional level.

A commemorative article about him will be written
for SIAM News. For the preparation of that article,
I would greatly appreciate receiving, by email or
by letter, any input you would have for such an article.
The input can consist of personal anecdotes, about professional
interactions, his role and influence in our community,
especially w.r.t the sparse matrix community, etc. Please
just send to me anything that you feel might be useful.
Please send this material to me at
MS B256, CCS-3
Los Alamos National Laboratory
Los Alamos, NM 87545

before November 15th

His wife, Nona, sent the following obituary. If you
would like to send condolences to her. Her address is

Nona C. Willoughby
4467 Terra Granada Drive
#2B, Entry 15
Walnut Creek, CA 94595-4031
Phone: 925-932-8694

I am sure that she would greatly appreciate your notes.
(I do not have an e-mail address for her.)

Obituary From Nona

Ralph Arthur Willoughby, Ph.D., passed away peacefully on
July 21, 2001 with his loving family and Hospice support at age
77 in Walnut Creek, CA. He spent his childhood and youth in
Nevada City and Yuba City. After serving in WWII he
returned to the University of California where he met his wife Nona.
Together they rebuilt several honor societies including Phi Beta Kappa.

After receiving his Mathematics from UC Berkeley, Ralph
took a teaching position at Georgia Tech University in Atlanta and
worked at the Oak Ridge Laboratory during the summers. In 1955,
he joined Babcock and Wilcox in Lynchburg VA as a mathematician
in charge of atomic energy research. Two years later he joined the
IBM Research Center in Yorktown Heights, NY where he was a mathematician
for 32 years. In 1991, Ralph and Nona retired to Rossmoor in Walnut
Creek, CA. To be near their daughters.

Ralph was a prolific writer and reviewer for professional journals,
independent symposia, and books, specializing in sparse matrices and
Lanzos algorithms for large symmetric eigenvalue computations. He
also hosted numerous international conferences.

Ralph is survived by his wife Nona of 54 years, daughters Carol and Ann
Willoughby, grandsons James and Paul Abers, his sister Eleanor McFadden
and sons, and his brother, Peter Putnam, MD and his two children.

Remembrances can be made in Ralph's honor to the scholarship fund at
UC Berkeley.

Subject: Birthday of Francoise Chatelin

Francoise Chatelin comes of age

The youthful vigour of Francoise Chatelin nearly resulted in her 60th
birthday passing without due recognition. We are delighted to record
that Madame Chatelin reached this milestone on September 21st.
In her long and distinguished career, which we should add still continues at
the University of Toulouse and CERFACS, Professor Chatelin has fathered
(we should say mothered) no fewer than thirty graduate students, several
of whom have themselves continued to distinguished careers. It is with
great pleasure that we ask you to join with us in wishing Francoise many
happy returns.

Subject: SIAM Outreach Membership

SIAM discounts membership dues for individuals in developing countries

In 1999, the SIAM Board of Trustees approved an affordable
membership option for individuals who live and work in developing
countries (as identified by the World Bank). This category of
membership, SIAM "outreach membership," was created to help make
SIAM products and services accessible to a wider and more global
group of applied and computational mathematicians. This is a great
alternative for individuals in developing countries who cannot
afford the full SIAM dues. For just $25 per year, eligible
individuals receive a slightly reduced set of benefits.

Outreach Members receive all print issues of SIAM News and
electronic-only access to SIAM Review. They can join any of the SIAM
Activity Groups at $10 per group, are entitled to the member discount
of 30% off list prices on all SIAM books, and receive member
discounted registration at SIAM sponsored meetings. No additional
journal subscriptions at membership rates are available as part of the
Outreach Membership.

The Outreach Membership application (secure) form can be found at

the ICIAM 2003 Conference in Sydney, Australia, and so as not to clash
with the SciCADE Conference in Trondheim, Norway. To summarize, the dates
for these three events are:
30 June 2003 - 4 July 2003: SciCADE Conference, Trondheim, Norway
7 July 2003 - 11 July 2003: ICIAM Conference, Sydney, Australia

Subject: Short Course at Cambridge on Computational Differential Equations

New Trends in Computational Differential Equations
LMS/EPSRC Short Course
University of Cambridge, 24-28 March 2002

The purpose of the short instructional course is to expose research
students, mainly (but not exclusively) from the applied and
computational community, to new trends in the discretization of
differential equations. Just about every applied-mathematics, science
or engineering dissertation these days involves a substantive (and
often dominant) computational component. Our intention is to provide
participants with an opportunity to familiarise themselves with new
computational approaches and to examine how do the latter fit into
their own research interests.

The lecturers and course titles are:

Adaptivity and geometric integration: Chris Budd (University of

Multiresolution methods for partial differential equations:
Wolfgang Dahmen (RWTH Aachen)

Approximation theory for numerical computation: Ron DeVore
(University of South Carolina)

Partial differential equations in image processing, computer
vision, and computer graphics: Guillermo Sapiro (University of

A central feature of computational methods is their great
applicability to virtually all areas of scientific, engineering and
medical research. Thus, the presentation will not be restricted in
contents and language to `hard core' mathematicians, with an interest
in algorithms as mathematical constructs. Every attempt will be made
to make the short instructional course useful and relevant to students
in application areas, who view numerical methods as tools in their own

Accommodation and subsistence in Cambridge are free to all UK-based
research students, but there will be a registration fee of GBP 60.
EPSRC-funded students can expect this fee and their travel costs to be
funded from departmental grants.

Non-UK-based research students and participants who are not research
students will be expected to pay the registration fee of GBP 60 and, if
required, GBP 245 for accommodation and subsistence. There will be four
bursaries (covering accommodation, subsistence and, in case of
hardship, registration fees) for non-UK based research students.
