However, this title could lead some readers to think of the multigrid conferences at Copper and to disregard the message. A more complete title would be "Copper Mountain Conference on Iterative Methods", which would better reflect the broader coverage of the meeting.

H. Wilkinson Fellowship in Computational Mathematics. This fellowship was created in memory of Dr. James Hardy Wilkinson, F.R.S., who for many years had a close association with the Mathematics and Computer Science Division at Argonne, where he acted as a consultant and guiding spirit for such efforts as the EISPACK and LINPACK projects. The Wilkinson Fellowship is supported by a special grant from the Applied Mathematical Sciences subprogram of the U.S. Department of Energy. The J. H. Wilkinson Fellowship is intended to encourage young U.S. scientists who are actively engaged in state-of-the-art research in computational mathematics-including, but not limited to, the development and implementation of numerical algorithms for linear algebra. The candidate must be a U.S. citizen or permanent resident, must have earned (or be about to earn) a Ph.D. degree or the equivalent during the past five years, and should have a strong background in numerical computation. The candidate should also be interested in expanding into the area of advanced computing research. Argonne's Mathematics and Computer Science Division has strong programs in computational mathematics and advanced computing, as well as in software engineering and applied analysis. This appointment is for one year, and may be renewed for a second year. It includes a highly competitive salary, moving expenses, and a generous professional travel allotment. Applications from qualified candidates, as well as nominations for the position of Wilkinson Fellow, should be addressed to Rosalie L. Bottino, Employment and Placement, 9700 South Cass Avenue, Argonne National Laboratory, Argonne, IL 60439-4832. Applications should include a resume and a statement of research goals, and the names of three references. The closing date for applications is December 1, 1989. The applications will be reviewed by an international selection committee and a candidate announced in January 1990. The position will commence during 1990. Further inquiries can be made by calling 312-972-7162 or by sending electronic mail to more@mcs.anl.gov. Argonne is an affirmative action/equal opportunity employer. ------------------------------ From: Reginald Tewarson Date: Mon, 21 Aug 89 15:06 EDT Subject: Position at Stony Brook State University of New York at Stony Brook Department of Applied Mathematics and Statistics The Department of Applied Mathematics and Statistics anticipates a post-doctoral and/or a tenure track Assistant Professor position starting January 1990.

Have you won an award or been appointed or elected to a new position? Your colleagues in SIAG/LA would like to know. Please mail this information to me at pgcoxson@lbl.gov. If I receive it by the September 10, I can include it in the next newsletter. Thank you very much for your cooperation. Yours sincerely, Pam Coxson Secretary, SIAG/LA pgcoxson@lbl.gov ------------------------------ From: Pat Gaffney Date: Thu, 24 Aug 89 17:42:26 EMT Subject: IBM Bergen Active in Environmental Sciences IBM chooses Bergen for activities in Environmental Sciences To emphasize its commitment to the environment IBM has appointed its Bergen Scientific Centre -- as the centre for IBM's activities within environmental modelling and as the focal point for information on environmental activities throughout Europe. "IBM in Europe has long recognised the importance of environmental protection and we are committed to helping governments and other industries to develop solutions to environmental problems when opportunities present themselves and when IBM knowledge, experience and technology can be helpful," said Dave McKinney, president director general, IBM Europe. "The Bergen Scientific Centre is part of IBM's initiative". Norway was chosen as the host for this international activity because of its initiative and position in environmental protection work and because of the close partnership between the Scientific Centre and the University of Bergen and surrounding institutes. The Bergen Scientific Centre, which was established in 1986, has gained an international reputation for its work in Offshore Technology (Reservoir and Seismic processing), Oceanographic Modelling, and Information Technology. This new initiative will capitalize on the available expertise and accomplishments of the Centre while at the same time strengthening and expanding the effort to include a broader coverage of environmental work. The main topics that will be covered by the new Environmental Sciences activity will be: Modelling, Databases, Remote Sensing and Mapping. The Scientific Centre will be focal point for information on all work conducted in the above topics both inside and outside IBM. In conjunction with academic and industrial partners the Centre's Environmental Sciences activity will concentrate on modelling, the coupling of databases with modelling and simulation, and remote sensing. A key ingredient for the success of this new activity is the cross fertilization that is to be accomplished from the Information Technology work conducted by the Centre. In particular Parallel Computing will be used as a major component of the modelling and simulation work within Environmental Sciences. Other areas of Information Technology, that will play a key role in the Centre's Environmental Sciences, include: Expert Systems and Databases. By collaborating with other international scientific organizations, both inside and outside IBM, the Scientific Centre aims to coordinate and strengthen its own activities within Environmental Sciences while at the same time contributing to international collaboration. The planned expansion in the areas of modelling and databases, and the heavy emphasis on parallel computing imply that sufficient computing power and storage facilities are available for the Centre's staff and partners. In this regard the main computing power of the Centre will be tripled by expanding the Centre's IBM 3090-200 VF to an IBM 3090-400S with 4 vector facilities and 80 gigabytes of disk storage. In addition the Centre will increase its staff to provide more student and faculty positions. ------------------------------ From: Stanly Steinberg Date: 24 Aug 89 20:54:15 GMT Subject: Symmetric Discretization Problem I am interested in numerically solving general elliptic pde's in a unit cube in n-variables with general Robin boundary contitions. The partial differential equation: n __ d d \ -- a (x) -- f(x) + b(x) f(x) = g(x) /_ dx ij dx i j i=1 j=1 0 < x < 1 i The boundary conditions: n __ d A(x) \ N a (x) -- f(x) + B(x) f(x) = C(x) /_ i ij dx j i=1 j=1 Here a(x) is a symmetric matrix and N is a vector normal to the boundary. Of course f is to be found and a, b, g, A, B, and C are given. Main Question: Can this problem be discretized using a nearest-neighbor finite-difference scheme in such a way that the approximation is second order and the resulting linear system is symmetric? First order and symmetric? Remark: Nearest-neighbor means that the number of points in the finite-differrence stencil is 3**n. Remark: For n=1 the solution is easy. For n=2 or n=3, many special cases can be done. A single algorithm is needed for the full problem class. Question: How about a finite-element method? Remark: The problem appears in this form because boundary-fitted solution-adaptive grids are being used to solve a steady-state problem.
