**Subject: Conference Honoring Ake Bjorck**

FIRST ANNOUNCEMENT AND CALL FOR PAPERS

In celebration of Ake Bjorck's 60'th birthday a conference will be

held at Linkoping University, January 9-10, 1995. The theme of the

conference will be

LEAST SQUARES METHODS: THEORY, ALGORITHMS and APPLICATIONS

The aim of the conference is to celebrate the many contributions of

Ake Bjorck to numerical analysis. This is best done by bringing

together scientists working in the field of numerical linear algebra

to discuss the latest development concerning least squares methods.

It is an interesting coincidence that in 1995 it will be 200 years

since the the least squares method was first used (according to Gauss

in his dispute with Legendre).

The following speakers have agreed to give a talk:

Iain Duff Rutherford Laboratory and CERFACS

Gene Golub Stanford University

Chris Paige McGill University

Haesun Park University of Minnesota

Mike Saunders Stanford University

Pete Stewart University of Maryland

Charles Van Loan Cornell University

Jim Varah University of British Columbia

In addition there will be a number of contributed 20 min. talks.

No conference proceedings will be published. Participants and

contributors should notice the following dates.

June 1, 1994 Second announcement

September 1, 1994 Deadline for paper submission

October 15, 1994 Notification of acceptance

November 15, 1994 Final date for registration

January 9-10, 1995 Conference

A conference dinner and birthday party will be held on the evening of

Monday, January 9.

ORGANIZING COMMITTEE: Lars Elde'n and Tommy Elfving, Linkoping, Gene

Golub, Stanford, Bo Kagstrom, Umea, and Axel Ruhe, Gothenburg.

**Subject: Mathematicians on Coins and Bills**

I am interested in knowing of any coins or bills

that have a mathematician's picture on them.

The German two-mark coin, for example, shows Max Planck

(I know he's really not a mathematician per se, but a

physicist of that stature sure comes close!)

I would appreciate hearing from you if you know.

**Subject: 1994 SIAM Forum - Mathematics in Industry**

1994 SIAM FORUM MATHEMATICS IN INDUSTRY: THE JOB MARKET OF THE

FUTURE July 23, 1994 Holiday Inn at the Embarcadero, San Diego,

California

Panel sessions and presentations for mathematicians in business,

industry, government, and academia will focus on The Job Market

of the Future:

Mathematics in Smaller Firms A panel discussion of practices,

opportunities, and experiences of mathematicians working in

smaller firms, a rapidly growing segment of American business.

Experiences of Recent Industrial Hires Brief presentations and

discussions from some who recently started working in industry.

How did they find their positions? What do they do? What do

they wish they knew in graduate school that they know now?

Hiring: the Manager's Perspective Managers discuss the processes

and practices of hiring industry and government. Who makes the

decisions and how? What are current needs, practices and

opportunities? Who is getting what kinds of positions?

Bridging from Academia to Industry How do academic

mathematicians build bridges to industry? What programs are

available for student and faculty internships in industry and

government? What support can university relations offices

provide? How are alumni networks built?

Non-Mathematicians Who Do Mathematics In Industry Many

individuals whose terminal degrees are not in mathematics work

in industry as applied mathematicians. How did they come to

applied mathematics? What kinds of problems do they work on?

How did they get their positions? What can those with

mathematics degrees learn from their experiences?

The Forum is sponsored by SIAM to promote exchange within the

community on important issues and to inform and energize it.

Extensive audience participation is always a key feature of the

SIAM Forum. Informal meals and receptions will offer further

opportunities for interaction and networking.

This forum is being conducted with partial support from the

Department of Energy.

Dear Colleagues,

The final plans for the Multi-Domain Workshop 94 are being drawn up

and we are looking forward to the event. Please note that the

registration fee for the event has been reduced to $60 ($50 for

grad students). All who have registered at the previous amount

Announcement for Spectral Multi-Domain Methods Workshop

May 16-18, 1994

Center for Research in Scientific Computing

North Carolina State University

Raleigh, North Carolina, USA

Topic: Spectral multi-domain methods. A major theme will be the topic

of interface conditions. There is an intricate balance between what

happens at the interfaces and the trade-offs between the discrete-

ization and the actual implementation. This is further compounded

when considering different computational architectures. Other topics

will include how to implement the methods and some basic results. The

presentations will begin with an introduction to the techniques and

will include some of the latest results to this growing field. Our

primary interest is to provide a forum for attendees to freely

exchange ideas with a view to collaboration.

Format: We anticipate each speaker providing an introductory lecture

and a lecture on their area of expertise. The introductory lectures

can be coordinated so that topics central to spectral multi-domain

techniques are covered. Presentations are limited to the invited

speakers; however, there will be a poster session. Also, the number

of attendees will be limited in the interest of providing a more

intimate setting.
