Jerry began his work on Mathematica in 1987, and laid the foundations for most of the numerical capabilities of the system. He pioneered major new approaches in numerical analysis, implementing them in Mathematica, as well as using them in papers that he published about topics such as the Riemann zeta function. (He was largely responsible for the 1990 Mathematica poster of the zeta function.) Jerry will be known to many for his book "Elementary Numerical Computing with Mathematica", as well as for his lectures, papers and participation in newsgroups. His tragic death in the prime of his life is a great loss not only to those who knew him personally, but also to the world of mathematics and computing at large. In addition to having a superb intellect, Jerry was also a remarkable human being whose life continually demonstrated the deep spiritual and philosophical principles that guided him. I and his many friends will miss him greatly. We have set up the alias keiper-memorial@wri.com for mail about Jerry that can be shared with his family, friends and colleagues. We will be posting a more extensive obituary shortly. -- Stephen Wolfram ------------------------------ From: David Wille Date: Mon, 16 Jan 1995 8:52:59 MET Subject: Reports on ODE Stepsize Control Dear NA-digest readers, I wish to make a brief announcement for two technical reports on stepsize control now available electronically by ftp: "New stepsize estimators for linear multistep methods" Numerical Analysis report 247, David R.

First, on January 9/10, a conference on least squares computations celebrating Ake Bjorck's 60th birthday was held in Linkoping, very well organized by Lars Elden and Tommy Elfving, assisted by the staff of their department. About 70 people attended, including many from North America and Central Europe. Invited talks were given by Gene Golub, Iain Duff, Pete Stewart, Sabine van Huffel, Chris Paige, Jim Varah, Charles van Loan, and Michael Saunders. In addition, there were over 20 contributed talks, making it a very full two-day meeting. Particularly notable, in this reviewer's estimation, was Charlie van Loan's talk on the use of Kronecker Products in matrix decompositions, including new applications in wavelet transformations. A conference dinner in Ake's honor was held on the evening of January 9, at the Frimurare Hotel, in true Swedish style, with the President on Linkoping University, Sven Erlander, presiding. Many testimonials to Ake's work and generous nature were given. He was summed up by more than one observer as "a true Swedish gentleman". Note: several of the papers presented at the conference are available on WWW - use http://math.liu.se/Num/conference/ Second, from January 11-13, a conference honoring Germund Dahlquist's 70th birthday was held at the Royal Institute in Stockholm, ably organized by Lennart Edsberg, Bengt Lindberg, and the staff of NADA. Unlike the event 10 years ago celebrating his 60th birthday, this one was not intended to be a major conference. However, there were still over 70 attendees, many from North America and other parts of Europe (and John Butcher from New Zealand!). Hour-long invited talks were given by Gene Golub, John Butcher, and Heinz Kreiss, and there were as well 25 twenty-minute talks, thus filling up the two and a half day schedule. Again the conference dinner Thursday night at the Vardshuset on the KTH campus was most entertaining, with 12 testimonials given to the breadth and depth of Germund's contributions to the field, and to his support of other researchers. The evening culminated in the singing of a special "Ode to Germund", written specially for the occasion. Jim Varah ------------------------------ From: Seiji Fujino Date: Thu, 19 Jan 1995 15:39:45 +0900 Subject: Who are Seidel, Hessenberg and Jordan? Who are Seidel ?, Hessenberg ? and Jordan ? Most of numerical analysts know the Gauss-Seidel method of the iterative method, the Hessenberg matrix in eigenvalue problem and the Gauss-Jordan method for the direct method for linear systems. I do, however, wonder who is Seidel, Hessenberg and Jordan ? Concerning Seidel as a designer of the Gauss-Seidel method, from the book titled 'Valeurs propres de matrices' by Francoise Chatelin published by Masson Paris 1988. In chapter 2.12 of the book, we can see that Philipp Ludwig Seidel(1821-1896) was born at Zwiebr\"ucken and died at M\"unchen. Moreover, we know that his original paper of the Gauss-Seidel method is the following paper. \"Uber ein Verfahren, die Gleichungen, auf welche die Methode der kleinsten Quadrate f\"uhrt, sowie lineare Gleichungen \"uberhaupt, durch successive Ann\"aherung aufzul\"osen, Abh. bayer Akad. Wiss., {\bf 11}(1874), 81. However, I want to know on his personal data in detail. Concerning Hessenberg as a designer of the Hesssenberg matrix in eigenvalue problems, from the book written by G\"unther and H\"ammerlin titled "Numerical Mathematics" published from Springer Verlag 1991(English translation), we can see that they refered K. Hessenberg (1941) in page 97 of the book as a designer of Hessenberg matices, and listed in the reference(page 409): "Auflosung linearer Eigenwertaufgaben mit Hilfe der Hamilton-Cayleyschen Gleichung. Dissertation T. H. Darmstadt" by K. Hessenberg(1941). Does anybody have his dissertation itself? Concerning Jordan as a designer of the Gauss-Jordan method of the direct method for linear systems, I do not know except that he might be German. In chapter 1.6.3 of the above book by F. Chatelin, we see that Jordan as a designer of Jordan normal form is French Camille Jordan(1838-1921). He was born at Lyon and was died at Paris. However, we cannot know anything from this book about Jordan himself of the Gauss-Jordan method and his original paper and his works? So, what I want to know is on their personal information in detail and their works relevant to the method. Does anybody have knowledge on this matter? Thanks a lot in advance!

It's slow, but works quite well. The routine - called MyDiv - is nchased within a program (in two flavours, Turbo Pascal and C) which also performs the following tests: First test: (5505001/294911)*294911 - 5505001 Second test: (4195835/3145727)*3145727 - 4195835 The performance of MyDiv is compared with the compiler instruction "/" and with tbe coprocessor's (defective) FDIV instruction. If you are willing to get a copy of the code please send a mail to: barbuto@ax.ibase.org.br (in Portuguese or English) specifying which version you want to receive, Pascal or C, and I'll send it to you as soon as possible.

Present ABS literature has more than 250 works and numerical experiments have shown that these methods can be implemented in a numerically stable way and can be faster than standard methods on vector/parallel machines. Following a first conference in Luoyang, the second ABS conference is planned in Beijing, June 1-3. Notice that the optimization ICOTA conference is planned for June 5-8 in Chengdu. Registration fee is 250 US$, including lunches and dinner banquet. Papers in the area or in related linear algebra and optimization areas are invited. Proceedings will be published.

The conference will focus on curve and surface design, solid modeling and computer-aided design and manufacturing, geometric algorithms, and applications in such areas as computer vision, geosciences, graphics, medical imaging, robotics, and scientific visualization. What is New About the Conference? In response to requests from attendees of previous meetings, there will be several changes in the format of the conference. First, the length of the conference will be reduced from 5 days to 4. The number of parallel sessions will also be reduced from 4 to 2 for Minisymposia, and from 4 to 3 for Contributed Focus Sessions. The challenge to the organizing committee was to provide a forum for all SIAM members to present their research within a format with fewer days and fewer parallel sessions. As in the past, there will be no refereeing of papers. We believe in the free and immediate flow of ideas. However, to accomplish this organizational feat, we have redirected the minisymposia, changed the format of the contributed sessions which will now be called Contributed Focus Sessions, and reinstated the poster session.
