**Subject: Open Directory Project, Numerical Analysis**

The Open Directory Project is a kind of encyclopaedia of WWW links.

It is one of the main sources for search engines.

When I checked a few minutes ago, it had:

1,825,441 WWW links

25,768 editors

277,729 different categories

Point your web browser to:

http://dmoz.org/

to see the current numbers at the bottom of the home page.

One of those categories is Science:Math:Numerical_Analysis

That category needs an editor.

Any volunteers?

If you look at the category Science:Math you find:

Those numbers in brackets are the numbers of links.

Notice in particular:

Logic (490)

Statistics (382)

Number Theory (326)

Numerical Analysis (39)

The first 3 of these categories each have editors who have collected

links. Numerical Analysis does not have an editor, though there is

an editor for the Software subsection under NA, and most of the 39

links are under this sub-category.

The home page gives details on how to become an editor.

N.B. I am the editor for the Fortran:Source_Code category.

SECOND ANNOUNCEMENT and CALL FOR PAPERS

The Ninth International Workshop on

Matrices and Statistics

In Celebration of C. R. Rao's 80th Birthday

NIWMS-2000

Hyderabad, India: December 9-13, 2000

The Ninth International Workshop on Matrices and Statistics, in

Celebration of C. R. Rao's 80th Birthday, will be held in the

historic walled city of Hyderabad, in Andhra Pradesh, India, on

December 9-13, 2000.

The program will start with a two-day course on recent advances

in Matrix Theory with Special Reference to Applications to

Statistics on Saturday, December 9, and Sunday, December 10, 2000.

This will be followed by the presentation of research papers in

the Workshop proper on Monday, December 11--Wednesday,

December 13, 2000; it is expected that many of these papers will be

published, after refereeing, in a Special Issue on Linear Algebra

and Statistics of Linear Algebra and Its Applications.

Organizing Committees

International Organizing Committee:

R. W. Farebrother (Victoria University of Manchester, UK),

S. Puntanen (University of Tampere, Finland),

G. P. H. Styan (McGill University, Canada; vice-chair)

H. J. Werner (University of Bonn, Germany; chair).

Local Organizing Committee:

R. Bhatia (Indian Statistical Institute, Delhi Centre),

P. Bhimasankaram (Indian Statistical Institute, Hyderabad),

V. Narayana (Indian Statistical Institute, Hyderabad),

M. S. Rao (Osmania University, Hyderabad),

B. Sidharth (Birla Science Centre, Hyderabad),

U. SuryaPrakesh (Osmania University, Hyderabad),

R. J. R. Swamy (Osmania University, Hyderabad),

P. Udayasree (University of Hyderabad),

K. Viswanath (University of Hyderabad).

This Workshop is being organized in Hyderabad by the Indian

Statistical Institute and the Society for Development of

Statistics, in collaboration with the Birla Science Centre,

Osmania University and the University of Hyderabad.

We expect that the Short Course will cover numerical linear

algebra, as well as generalized matrix inverses (including

Campbell-Youla, Drazin, group and Moore-Penrose inverses),

matrix partial orderings (including Loewner, minus and sharp

orders), matrix inequalities (including inequalities for

determinants, traces, eigenvalues and singular values), together

with statistical applications. In addition, we expect that there

will be a session on statistical proofs of matrix results, as

well as sessions on linear statistical models, on random matrices,

and on matrices with special reference to applications in

educational testing, electrical engineering, and to psychometrics.

The Short Course will be followed by the Workshop proper, which

will include the presentation of both invited and contributed

papers on matrices and statistics. There will be also a special

session for papers presented by graduate students. We expect that

the topics to be covered will be similar to those covered by

several Special Issues on Linear Algebra and Statistics of Linear

Algebra and Its Applications.

More details on this Workshop are given in the latest issue of

IMAGE (no. 24, pp. 18-19, April 2000) and are updated regularly
