Subject: Request for a "Tough" 2-point BVP
Some statisticians here at the ORNL have developed a numerical
technique for solving two point boundary value problems for linear
second order ODE's. A thumbnail description of their method would
include the words "global" and "collocation," but to tell the truth
I don't really understand it. They claim they are taking the mean
of a collection of functions that satisfy the ODE at the collocation
points which they call "enforcement sites." At any rate, I have given
them a stiff ODE, and one with a regular singular point at x=0. On
these they have done remarkably well. Now they want a really tough
problem. Sooooo, who would like to volunteer a tough problem for this
experimental method? I know, how tough can a linear problem be? But
they're not up to y" = F(x,y,y') yet. Maybe next year. D. G. Wilson,

Japan SIAM Established
Japan SIAM (Japan Society for Industrial and Applied Mathemtaics) will start
next spring as a new academic society in Japan. Its aims and scope are to
bring together the researchers, eigineers, instructors and all others who are
engaged in and/or apply mathematical method and idea to their problems, and
to promote the academic activity in this field in Japan.
Recently Japan has been recognized as a country of high technology,
including computers and its applications, which can be brought in by the
progress in mathematical sciences. Such situation will surely intensify in
the future, when technology needs more mathematical method and idea to make
breakthrough in highly difficult technological barrier. This comes from
the fact that without mathematics, which is known as an almost unique
language in science and technology, it is impossible to apply many
methods of analysis devised in some specific fields for all other fields.
At the same time, the situation encourages a number of pure mathematicians
to turn their attention to the problems in science, technology and
Considering all issues mentioned above, Japan SIAM will be a platform
of discussions and communications between its members interested in the
application of mathematical sciences. It will act like as SIAM (USA),
IMA (UK), SMAI (France) and GAMM (Germany).
Now the establishment committee of Japan SIAM, leaded by Prof. Masatake
MORI, University of Tokyo, is arranging necessary affairs for its start-up,
activity, journal and so on. Its current focus is on the founding assembly
to be held in the coming April in Tokyo.

Subject: Change of address for D. G. Wilson
I will be leaving the Oak Ridge National Lab at the end of this year
to take a new job with IBM in Kingston, New York. I will be working
on the numerics of software for the IBM 3090. I haven't started yet,
so I don't really know what I'm getting into, or what I can and can't
accomplish. However, if you have comments about or suggestions for
improvement in 3090 software (or hardware for that matter), I would
be glad to receive them and to dicuss them with IBM folks in Kingston
when I get there. I will be at the ORNL through December 28. I plan
to take vacation in January, but in February my address will be:
Dr. David G. Wilson
IBM, Dept. 41UD, MS 276
Kingston, NY 12401
I hope to have an e-mail address, but I don't have one yet. Happy
holidays to all. George Wilson.

Subject: Scientific Computing / Computational Mathematics at Stanford
I attach a brief summary of our Scientific Computing/ Computational
Mathematics (SC-CM) Program at Stanford. If you have any students who might
be interested in this program, please encourage them to apply. Thanks.
I'd be happy to hear of other programs of this nature.
HISTORY AND PURPOSE. The Scientific Computing and Computational
Mathematics Program came into being three years ago. Its purpose was
to train students in the use of modern computer architectures for
solving problems arising in science and engineering. We sought to fuse
a discipline which contained components of computer science, applied
mathematics and application areas. The Program is an indepedent
program which admits students independently of any department. At the
same time, several of the faculty (Golub and Oliger) are members of
the Computer Science Department and, hence, teach and advise students in
CS. The Program was originally under the Dean of the Graduate School
but has recently moved to the School of Engineering where more
resources were made available. In general, there has been much
enthusiasm for this program at Stanford from members of the School of
Engineering and faculty members in the applied sciences.
FACULTY. The faculty of the Program is three-tiered. The core
faculty consists of G. Golub, J. Keller and J. Oliger. There are
several members of the associate faculty and the affiliated faculty.
I am pleased to say that there has been a great deal of good will from
these faculty members. They have contributed in several ways such as
supporting and advising students.
STUDENTS. There are now 15 doctoral students in the new program.
For this academic year, ten new students came from an applicant pool
of over 40 (12 students were made offers of admission to the program).
These students have a variety of backgrounds, including medicine,
computer science and chemical engineering. We hope to expand our
applicant pool through advertising and word of mouth. The students are
supported in a variety of ways: teaching assistantships, research
assistantship, an NSF and an SOE fellowship. We actually have more
positions than are being filled, but this will no doubt change. We
are beginning an affiliates program from which we hope to support
students in the future. In addition to the Ph.D. program, we have a
master's degree program with about six students who are mainly

Subject: Conference in Finland on Numerical Solution of ODE
THE 1990 CONFERENCE
JUNE 18-22, 1990
This meeting continues the tradition of the 1986 and 1988 ODE meetings in
Albuquerque and Toronto. There will be a small number of principle talks
by invited speakers on a range of subjects, such as
*stability of matrix products
*real-time simulation of mechanical systems
*Runge-Kutta methods for stiff ODEs and DAEs
*computation of invariant sets, and numerical estimation of Hausdorff
dimension for attractors.
In addition there will be twenty-minute contributed presentations, and a
limited number of forty-minute highlighted talks, selected on the basis of
submitted abstracts. Abstracts for either talk category should be one page
in length (approximately *300-500 typed words*), and should appear with title
and author list in a form suitable for inclusion in the conference program.
All abstracts should be sent by regular mail. If the abstract is being submitted
as a highlighted talk, a separate letter should accompany the abstract,
stating why the talk would be especially suitable for a longer presentation.
The deadline for abstract submissions is **January 31, 1990**.
A limited amount of *financial aid* is available, to be awarded principally
on the basis of *need*. Applicants for such support should accompany their
abstract with a separate *brief* letter stating very clearly why they merit
support and the exact minimum amount which would enable them to participate.
As part of the Special Year on Numerical Analysis, the meeting is being
sponsored by Finland's Rolf Nevanlinna Institute. The Rolf Nevanlinna Institute
is a national research center with activities in both basic and service research
in all fields of pure and applied mathematics. Additional funding is being
provided by the Finnish Ministry of Education.

School of Mathematical Sciences
Research Positions in Advanced Computation
The School of Mathematical Sciences intends to provide a new focus of
activity to augment its existing research in highly computer intensive
mathematical and statistical methods and to capitalize on its substantial
theoretical strength. The School includes , in particular, seven Fellows
of the Australian Academy of Science, and it has strong interactions with
related groups within the University. The University has good computing
facilities which include a Fujitsu VP-100 supercomputer.
Applications are invited from suitably qualified persons for appointment
as Postdoctoral, Research, or Senior Research Fellow within the special
areas of (1) computational mathematics, including applications to non-
linear modelling, or symbolic and exact computation, (ii) computer intensive
No teaching is required, but some participation in advanced under-
graduate and graduate teaching may be available.
Applications from those able to take leave of absence from their own
institution will be welcomed. Persons interested in fractional appoint-
ments are encouraged to apply. Expressions of interest are also invited
for a position to be funded jointly by the Division of Mathematics and
Statistics, CSIRO and the ANU. This post would involve collaborating with
Australian Industry to identify and solve important problems in computer
intensive statistical methods. It is expected that the appointee to that
position would divide his time between CSIRO, Melbourne and the ANU.
Enquiries and requests for information may be addressed to the Dean,
Professor C.C.Heyde (phone 61 (0)62 492957; FAX 61 (0)62 490759).
Closing date: 31 January 1990
SALARY: Senior Research Fellow $A 43,104 - 51,141 p.a.
Research Fellow $A 31,259 - 40,622 p.a.
Postdoctoral Fellow $A 27,139 - 30,882 p.a.
APPOINTMENT: Senior Research Fellow/Research Fellow up to three years with
a possible extension to five years; Postdoctoral Fellow normally two years
with possible extension to three years.
I would like to suggest that graduating Ph.D's and those interested a
period of intensive research might want to consider these positions care-
(1) For a combination of reasons the academic support both within the
School and outside it is as strong as you are likely to find anywhere.
Also there is considerable interest in the project (the School wants AC
recognised as one of its main activities, and major theoretical groups
in areas including Physics, Chemistry, Biological Sciences, Astronomy,
and Environmental Studies are strongly supportive - in part because of
encouragement being given to cooperative postgraduate programs, in part
because the initiative is seen as providing a valuable focus for an
important part of their activities).
(2) The University computing facilities are good (including both vector
and parallel architectures), and show signs of getting even better in
interesting ways as at least one major computer manufacturer flirts with
the idea of funding R&D on campus as an important part of their develop-
(3) The University is well equipped to accomodate research staff and
appreciates the need to fund transport of family plus goods and chatels
both TO AND FROM Australia. Most University housing is well situated
for public transport, schools (and preschools), and shops. Australia does
have a health scheme which covers at least basic needs.
(4) Canberra is a very attractive city which is very easy to live in. Also
food costs are lower and quality higher than in most comparable cities. If
you allow wine in the equation we win by miles!
(5) Recreational facilities are excellent. Canberra is also close to some
of the most beautiful and interesting country in Australia. It is a very
good centre from which to see it. One method which tends to be encouraged
is by bushwalking/backpacking.
I hope I have made this positions sound both interesting and worthwhile-
because that is certainly the intention. If you want further information
