Subject: Correction for Copper Mountain Announcement
Last week's NA Net News included an annoucement of a "Copper
Mountain Conference". 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.

Subject: Wilkinson Fellowship at Argonne
WILKINSON FELLOWSHIP IN COMPUTATIONAL MATHEMATICS
Mathematics and Computer Science Division
Argonne National Laboratory
Argonne National Laboratory is seeking outstanding candidates in
the general area of computational mathematics to fill the 1990
J. 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.

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.

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.
