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.

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 industry. 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. All the references should be to him: Prof. Masatake MORI Department of Physical Engineering Faculty of Engineering, the University of Tokyo Hongo, Bunkyo-ku, Tokyo 113, Japan.

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.

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. Gene 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 self-supporting.

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 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 statistical methods. 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- fully. (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- ment activity. (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.
