Subject: Origin of name "Hilbert Matrix"

A colleague, Grady Wright, asked me this one, which stumped both
of our google searches, so I thought I'd ask NA-Digest.

Did Hilbert first define it, or was it named for him for other reasons?

Best regards,

Bob Palais

Subject: Zhong-ci Shi Wins Hua Loo-keng Prize

Professor Zhong-ci Shi of Institute of Computational Mathematics of
Chinese Academy of Sciences was awarded the sixth Hua Loo-keng
Prize in Mathematics in the ninth National Congress of Chinese
Mathematical Society on October 31, 2003 in Wuhan, China. He is recognized
by his systematic and profound research in computational mathematics, in
particular his contributions in conforming and nonconforming finite element
methods. He is also recognized by his leadships in the development of modern
computational mathematics research in China.

The Hua Loo-keng Prize in Mathematics is the highest honor in Chinese
mathematical community. It was founded by Chinese Mathematical Society in
1992 to memorize the great mathematician, the late Professor Hua Luo-keng
(1910-1985).

Congratulations, Professor Shi!

Subject: Wanted: Solution for a Simple Riccati Equation

Hi,

I am looking for a solution to the following Simple Riccati Equation

X A X = B

where A and B are n by n SPD matrices, AB may not equal BA and the
solution X should be SPD as well.

Is there a closed form solution for 2x2 and 3x3 matrices? Or is
there a simple numerical solution?

Much appreciate any help.

SCOPE

The objective of the workshop is to bring together specialists
in the field of control of time-delay systems. High level contributions
on the many aspects of this research area, ranging from theory
over numerics to various applications, are awaited. Contributions on
related domains (e.g. control of uncertain systems, 2D and nD systems,
tele-operated control systems) will be considered with great interest,
provided they contain relations with time-delay systems.

In order to provide a joint forum for and create interaction between
specialists in control and numerical mathematics, and to increase
industrial participation, special attention will be paid to:

- Numerical methods for time-delay systems
- Applications, emphasizing delay effects in
telecommunication systems

This meeting is being held in conjunction with a workshop on Estimation
and Control Problems in Adaptive Optics
(www.ipam.ucla.edu/programs/ao2004 January 22-24, 2004).

This workshop on Mathematical Challenges in Astronomical Imaging will
focus on novel mathematical techniques in image reconstruction and image
analysis. New approaches to deconvolution will be explored, with
emphases on developments in multiscale, Bayesian, and wavelet methods,
on the varieties of point spread functions that characterize modern
astronomical instrumentation and on the constraints presented by
astronomical images. The goal of this workshop is to bring scientists
from the astronomical community together with mathematicians to explore
these issues.

to budgetary approval, are initially budgeted at the assistant professor level,
but candidates with proven research record may be considered at the
associate professor level. For assistant professorships, we seek strong
research potential and evidence of excellence in teaching. Research
productivity beyond the doctoral dissertation will normally be expected.
For associate professorships, applicants should have a good research
reputation and established research program, including success in securing
external funding, publication and supervision of graduate students.

Assistant professorships in computational biomathematics: While applicants
in all areas of computational biomathematics will be considered, those whose
research expertise and interests lie in one or more of the following areas
will be given preference: bioinformatics; computational genomics; Monte Carlo
and molecular dynamics simulations; biological and biomedical system
modeling; and biomedical signal and image processing.

Assistant professorship in mathematics: This position is open to any area of
mathematics; however, those whose research expertise and interests are in the
following areas will be given preference: educational technology development,
evaluation and implementation; information and data management; and
mathematics teaching and learning methodology research and experimentation.

Assistant professorship in applied mathematics: This position is open to any
area of applied mathematics; however, those whose research expertise and
interests are in one or more of the following areas will be given preference:
digital signal and image processing; statistical signal and array processing;
multidimensional signal processing; and mathematical neuroscience.

The successful applicants for all three positions will be expected to teach at
both undergraduate and graduate level, conduct research, advise students, write
grant proposals, collaborate with other faculty in the Department of Mathematics
and the College of Arts and Sciences. In addition, the successful applicant for
the general mathematics position is expected to coordinate instructional and
research activities in educational technology development and evaluation, and
information and data management. Applicants must have a Ph.D. in the
mathematical sciences or mathematically intensive field of a related discipline.
Applications will be reviewed beginning January 15, 2004, and the review will
continue until the positions are filled. Applicants should arrange to have a
curriculum vitae; three letters of recommendation; transcripts; a statement of
scientific or educational research expertise and interests; a statement of
teaching philosophy; abstracts of completed research (articles, software tools,

Subject: Research Position at University of Chicago

We are seeking someone with a Ph D in Mathematics with
experience in protein-protein interaction, dna-dna binding,
numerical solution of partial differential equations and modern
methods for machine learning (support-vector machines, boosting,
decision trees, neural networks). Programming experience
sufficient to implment the corresponding software is
necessary.

The employee will be a Research Associate in Computer Science,
funded by the Institute for Biophysical Dynamics. Salary will be
competitive and depend on qualifications. There will be funds
to travel to at least one meeting. The term of the appointment
will be at least one year, possibly renewable depending on
availability of funding.

The research to be done combines physical chemistry and
proteomics in a novel way, and applies it to biomedical
questions. The concept of dehydron will be explored in detail
by further statistical analysis of protein databases and
existing experiments. Mutations that correlate dehydrons with
disease (such as cancer) will be explored. Implications for
protein folding will be studied.

For more information on background research, see the papers
120-124 on the web site
http://people.cs.uchicago.edu/~ridg/lrsbib.html

No wet-lab experience is required, and there will be no
exposure to experiments with animals.

Applicants should send a CV and list of publications, and
have sent three letters of recommendation, to Nita Yack,
