Subject: Change of Position for Robert Voigt

I have left my half-time position at NSF. I will continue half-time as the
Director of the Computational Science Cluster at the College of William and
Mary where I can be reached at or (757) 221-2003. I
will spend the other half of my time working with the Department of Energy

Subject: New Methods for PDEs

Explicit and unconditionally stable algorithms
for PDEs in arbitrary regions

Dear Colleagues,

I have developed some new methods for initial/boundary value
problems of PDEs. So far, only tiny part of my research result has
been published due to some reasons (That was the work of couple years
ago). The developed methods have great advantages over those currently
used (Such as the Finite Element method) in solving time-dependent
problems(parabolic and hyperbolic equations). They are:

explicit-no simultaneous equations/no matrices,
computation is node by node straight forward;

second order accurate-reasonably accurate;

unconditionally stable-no restriction on step sizes for the sake of stability.

Besides, they are also naturally parallel algorithms. Obviously,
requirement on memory and CPU time can be significantly reduced because
of the above advantages.

In addition to the above, I am also doing research in other related
areas. In brief, my research consists of several topics:

1) Explicit and unconditionally stable algorithms for solving diffusion
equations in arbitrary regions;

2) Adaptive (explicit, unconditionally stable and second order accurate)
algorithms for hyperbolic equations;

3) Explicit and unconditionally stable algorithms for solving problems
with symmetric coefficient-matrices, such as the Maxwell equations.

4) Study on spectral stability analysis method (there are some problems
in the establishment of this analysis method. If interested, pleased
email me.) ;

5) ADI methods for solving diffusion equations in arbitrary regions and
stability analysis (the conclusion about the stability and
applicability of the ADI method is incorrect. Both complete analysis
and numerical examples are available);

6) Developing iteration algorithms for solving elliptic equations;

I have been doing research on this project by myself alone for several
years. I have solved some problems. However, in view of the scale of this
project and to accelerate research (e.g. coordinate transformation) in this
new area, I am looking for people who may be interested in this research.

I have prepared a report about my research with detailed formulae
(lengthy papers are also available). If you are interested in this research,
please email to


I can send the report (a MS Word file) via the Internet. I am also
pleased to answer queries about this research.

Subject: IMA Conference on Mathematics of Surfaces

University of Birmingham UK 31st August - 2nd September 1998

Computer-based methods for the construction, representation, and
manipulation of complicated surfaces have led to a wide interest in, and
need for, surface mathematics. Many applications now require the use of
surface descriptions, especially in such fields as computer aided design
and machining, and computer vision and inspection of manufactured parts.
The description of surfaces is also of interest in geographic information
systems and multimedia, and many other areas of science and medicine. This
diversity and the wide range of applicability of the subject have already
enabled the IMA to hold seven very successful conferences on the
mathematics of surfaces. The eighth such conference has now been scheduled.

Confirmed invited speakers include:
P. Besl (Silicon Graphics), R. Farouki (University of Michigan), H. Hagen
(University of Kaiserlauten), J. Hoschek (Technische Hochschule Darmstadt),
G. Lukacs (Hungarian Academy of Sciences), D. Manocha (University of North
Carolina), and H.-P. Seidel (University of Erlangen).

The call for papers has now finished, but persons wishing to attend should

Subject: Scholarships at Norwegian Univ. of Science and Technology

PhD Scholarships, NTNU, Norway
Strategic University Program
"Computational Science and Engineering"

NTNU has chosen "Computational Science and Engineering" (CSE) as their
"Strategic University Program" (SUP) for the coming six years. The program
is financed in full by the Norwegian Research Council. The program is based
on a collaboration between three faculties and will have an international
focus related to the development of the field (CSE) at NTNU. The project
contains visitor and postdoc fellowships.

In this program CSE is based on interaction between the areas of
mathematical analysis and modelling, numerical methods, computer science,
and marine fluid mechanics. The main elements will be parallel methods,
object oriented techniques, scientific visualization as well as modelling
and simulation of viscous flow.

In the first phase 5-6 PhD scholarships are announced. The research activity
will take place both separately in each faculty and through collaborating
research groups formed within the program. The PhD students will have access
to powerful resources for computing and visualization.

The successful applicants will take an interest in problems which belong to
the intersection between the areas of mathematics, marine fluid mechanics
and computer science.

The duration of the scholarships is at least 3 years. This period can be
extended to 4 years provided the student takes part in tutoring or other
activities requested by the department. The deadline for applications is May
1, 1998.
