**Subject: Pat Eberlein**

I have been asked by SIAM News to write about Pat Eberlein.

I would welcome stories and thoughts about Pat that you may have

to share for inclusion in this article. So many of us have special

memories of her, and I would like the article to reflect that.

Being her last student, I am a comparatively recent arrival

on the NA scene, and a rememberance of Pat would be incomplete

without stories from the "early days".

Thank you for your help,

Nil Mackey

**Subject: Fastest Fourier Transform in the West**

We are pleased to announce the release of FFTW 2.0, the latest version of

our C FFT library for real and complex transforms in one or more

dimensions. Source code and information for FFTW are available from:

http://theory.lcs.mit.edu/~fftw

The major change in this version is a completely-rewritten real-complex

transform library. The new library uses inherently real-complex algorithms

and specialized transforms of small sizes to achieve greatly-increased

speed.

Other new features include the use of O(N lg N) algorithms for large prime

lengths/factors. See http://theory.lcs.mit.edu/~fftw/release-notes.html

for a complete list of changes.

We also have released version 2.0 of our benchFFT benchmark, which now

benchmarks one and two dimensional real-complex transforms for many FFT

implementations. The benchmark, along with results from a number of

machines, can be found at:

http://theory.lcs.mit.edu/~benchfft

Cordially,

Matteo Frigo

**Subject: Prize for Achievement in Information-Based Complexity**

PRIZE FOR ACHIEVEMENT IN INFORMATION-BASED COMPLEXITY

This annual prize is for outstanding achievement in information-based

complexity. It will consist of three thousand dollars ($3,000) and a

certificate and will be awarded at a suitable location. The initial

prize committee will consist of Joseph F. Traub and Henryk Wozniakowski.

Anyone other than current members of the prize committee is eligible.

The members of the prize committee would appreciate nominations for the

prize. However, a person does not have to be nominated to win the award.

The deadline for the first award is March 31, 1999. (Please note that

this is a new date for deadline). The achievement can be based on work

done in a single year, a number of years, or over a lifetime. It can be

published in any journal, number of journals, or monographs.

This prize is separate from the Journal of Complexity's Best Paper Award.

**Subject: SIAM Student Paper Prizes**

SIAM Student Paper Prizes

The annual SIAM Student Paper Prizes will be awarded during the

1999 SIAM Annual Meeting, May 12-15, at the Radisson Hotel in

Atlanta, Georgia.

If you are a student or know of a student who would like to take

part in the competition, here are the details:

The authors of the three best papers in applied and computational

mathematics written by students and submitted to SIAM will

present their papers at the meeting and each will receive a

$1,000 cash prize as well as gratis registration for the meeting.

There is no provision for travel expenses associated with the

prize.

Papers must be singly authored and not previously published or

submitted for publication to be eligible for consideration. To

qualify, authors must be students in good standing who have not

received their PhDs at the time of submission.

In submitting their work for publication, authors are asked to

consider SIAM journals. However, student paper prize winners are

not guaranteed publication in any SIAM journal; all papers

submitted to SIAM journals are subject to the same refereeing

process and standards.

Submissions must be received in the SIAM office on or before

February 1, 1999.

Submissions, which must be in English, can be sent by regular

mail or fax. Each submission must include (1) an extended

abstract NOT LONGER THAN 5 PAGES (including bibliography); (2)

the complete paper, which will be used solely for clarification

of any questions; (3) a statement by the student's faculty

advisor that the paper has been prepared by the author indicated

and that the author is a student in good standing; (4) a letter

by the student's faculty advisor describing and evaluating the

paper's contribution; and (5) a short biography of the student.

Submissions will be judged on originality, significance, and

quality of exposition.

The winners will be notified by March 15, 1999.

Please direct your submission and any questions you may have to

**Subject: Hans Schneider Prize in Linear Algebra**

The Hans Schneider Prize in Linear Algebra

The Hans Schneider Prize in Linear Algebra is awarded by the International

Linear Algebra Society (ILAS) for research contributions and achievements

at the highest level in Linear Algebra. The Prize may be awarded for an

outstanding scientific achievement or for lifetime contribution. The Prize

is awarded every three years at an appropriate ILAS meeting, as decided

upon by the ILAS Executive Board. In any year in which a Prize is awarded,

there may be more than one recipient, within the discretion of the Board.

The first prize was awarded in 1993 to Miroslav Fiedler, Shmuel Friedland

and Israel Gohberg. The second prize was awarded in 1996 to Mike Boyle and

David Handelman (jointly), and to Robert Thompson (posthumously).

The funding for the Prize comes from the interest accruing on a large

donation made to ILAS by Hans Schneider and a number of small

contributions from other people.

The third prize will be awarded at the ILAS conference in Barcelona,

Spain, in July 1999. The Prize Committee consists of:

Angelika Bunse-Gerstner

Biswa Datta

Miroslav Fiedler

Russell Merris

Hans Schneider (chair)

Richard A, Brualdi (ILAS President, ex-officio).

Nominations are now being invited from members of ILAS and the linear

algebra community in general of distinguished individuals judged worthy of

consideration for the Prize. In nominating a person, the nominator should

include a brief biographical sketch together with a statement explaining

why the nominee is considered worthy of the Prize. The nominator should

include references to the publications or other contributions of the

nominee which are considered most significant in making this assessment.

Nominations received by Nov 15 will receive full consideration. They

should be sent to the chair of the committee
