Subject: Householder Award VI

The following announcement appeared in Numerische Mathematik and Linear
Algebra and its Applications. A corresponding announcement in the SIAM
News had obviously incorrect dates.


Announcement

Alston S. Householder Award VI (1987)

In recognition of the outstanding services of Alston Householder,
former Director of the Mathematics Division of the Oak Ridge National
Laboratory and Professor at the University of Tennessee, to numerical
analysis and linear algebra, it was decided at the Fourth Gatlinburg
Symposium in 1969 to establish the Householder Award. This award is
in the area in which Professor Householder has worked, and its natural
developments, as exemplified by the international Gatlinburg Symposia
[see A.S. Householder, The Gatlinburgs, SIAM Review 16: 340-343
(1974)]. Recent recipients of the award include Eduardo Marques de Sa
(Coimbra), Paul Van Dooren (Leuven), James Demmel (Berkeley) and Ralph
Byers (Cornell).
The Householder Prize VI (1987) will be awarded to the author of the
best thesis in Numerical Algebra. The term Numerical Algebra is
intended to describe those parts of mathematical research which have
both algebraic aspects and numerical content or implications. Thus,
the term covers, for example, linear algebra that has numerical
applications, or the algebraic aspects of ordinary differential,
partial differential, integral and nonlinear equations.
The theses will be assessed by an international committee consisting
of Shmuel Friedland (Chicago), Bill Gragg (Kentucky), Beresford
Parlett (Berkeley), Pete Stewart (Maryland) and Axel Ruhe (Gothenburg).
To qualify, the thesis must be for a degree at the level of an
American Ph.D. awarded between 31 August 1983 and 31 December 1986.
An equivalent piece of work will be accepted from those countries
where no formal thesis is normally written at that level. The
candidate's sponsor (e.g. supervisor of his research) should submit
five copies (if possible) of the thesis (or equivalent) together with
his appraisal to:

Ms. Doris Pool
Applied Mathematics Division
Argonne National Laboratory
9700 South Cass Avenue
Argonne, IL 60439, USA

by 28 February 1987. The award will be announced at the Gatlinburg X
meeting and the candidates on the short list will receive
invitations to that meeting.

WILKINSON FELLOWSHIP IN COMPUTATIONAL MATHEMATICS

Mathematics and Computer Science Division
Argonne National Laboratory

Argonne National Laboratory is seeking outstanding candidates in the
general area of computational mathematics to fill the newly created J.H.
Wilkinson Fellowship in Computational Mathematics.

This fellowship was created in memory of Dr. James Hardy Wilkinson,
F.R.S., who for many years had a close association with the Mathematics and
Computer Science Division at Argonne, where he acted as a consultant and
guiding spirit for such efforts as the EISPACK and LINPACK projects.

The J.H. Wilkinson Fellowship is intended to encourage young scien-
tists who are actively engaged in state-of-the-art research in computa-
tional mathematics-including, but not limited to, the development and
implementation of numerical algorithms for linear algebra. The candidate
must have earned (or be about to earn) a Ph.D. degree or the equivalent
during the past five years and should have a strong background in numerical
computation. The candidate should also be interested in expanding into the
area of advanced computing research. Argonne's Mathematics and Computer
Science Division has strong programs in computational mathematics and
advanced computing, as well as in software engineering and applied
analysis.

This one-year appointment includes salary (starting at $45,000; higher
with experience), moving expenses, and a generous professional travel
allotment. Applications from qualified candidates, as well as nominations
for the position of Wilkinson Fellow, should be addressed to Jack J.
Dongarra, Mathematics and Computer Science Division, Argonne National
Laboratory, Argonne, Illinois 60439-4844. Applications should include a
resume and a statement of research goals, and the names of three refer-
ences. The closing date for applications is April 1, 1987. The applica-
tions will be reviewed during April 1987 by an international selection com-
mittee, and an announcement made in May 1987. The position will commence
during September 1987.

Further inquiries can be made by calling 312-972-7163 or by sending
electronic-mail to dongarra@anl-mcs.arpa.

Argonne is an affirmative action/equal opportunity employer.

Subject: Eloge and Anecdotes for Jim Wilkinson

My name is JAN Lee, recently appointed as the Editor-in-Chief of
the Annals of the History of Computing. The journal, now in its
ninth volume, is published by AFIPS through Springer-Verlag.
Shortly after the death of Jim Wilkinson last year I was copied on
some of the anecdotes which were circulated amongst you. Unfortunately
no-one of my acquaintance has a complete set since I feel that your
commentsd and notes would form an excellent basis for an article
about Jim which might well accompany a more form eloge.

Is there anyone who did keep a complete record of that sharing of
experiences who would be (1) willing to share it with me to review
for possible editing and publication, (2) would be interested
in writing an eloge, (3) would be interested in adding to the
history of the profession in other subjects.

Annals has done a reasonable job over the past years in recording the
history of the early machines, has had a few excursions into the history
of software (mainly the languages such as FORTRAN and COBOL), and
some personal histories. The history of mathematical and scientific
computation is hardly touched. I realize that ACM will be holding a
conference on this topic in May 1987, but I also know that there is a
lot more than can be expressed in two-three days. I would be interested
in hearing of other events and activities.

Subject: Inquiry

Can anybody help with the following problem:
One has to find the complex roots of a polynomial of degree much
larger than 100, say of the order of 1000. The standard routines like
IMSL fail miserably. A very expensive solution is to diagonalize the
companion matrix of the polynomial, and this works up to about 500.
If you have the software, or information on where to get it, would you
please send it to
MAREK@SLACVM.BITNET
Thank you very much.
