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.

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.

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.

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 will be reimbursed for the difference. Sincerely, Kelly Black black@crsc1.math.ncsu.edu 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.
