After having left the University of Heidelberg I have now a joint position in Berlin both as full professor lecturing at the Free University and as head of the newly founded Konrad Zuse Center. The Konrad Zuse Center (in German: Konrad-Zuse-Zentrum fuer Informationstechnik Berlin, abbreviation: ZIB) is intended to be an institute for research and development in the general area of scientific computing / computer science. Main topics treated here are: Numerical Mathematics, Computer Graphics, Software Development, Symbolic Computing, Systolic Arrays and Algorithms, Distributed Systems and High Speed Networks. Of course, this is certainly a challenging task for the future to come. The emphasis of our research will be the development of efficient algorithms and user oriented software essentially for highly nonlinear systems, ordinary differential equations, differential algebraic equations, parabolic and elliptic partial differential equations. Technologically relevant applications are envisaged. As for the equipment, we run a CRAY X-MP/24 surrounded by smaller computers from IBM, CDC, Siemens, VAX, and a series of workstations. The use of our CRAY X-MP is shared with the two Berlin Universities and a number of universities in Northern West Germany. We are presently establishing world-wide cooperation with universities, research institutes, and industry. If you feel curious enough to visit, please let me know. The two addresses mentioned are: Konrad Zuse Center Heilbronner Strasse 10 D-1000 Berlin 31 and Mathematical Institute III Free University Berlin Arnimallee 2-6 D-1000 Berlin 33 Best regards to all of you Peter Deuflhard ------------------------------ Date: Mon, 14 Sep 87 14:06 EST From: Roger Horn <MSC_HRAH%JHUVMS.BITNET@forsythe.stanford.edu> Subject: June 1988 Linear Algebra Lecture Series at Johns Hopkins TO: NA@SCORE.STANFORD.EDU The Twelfth Mathematical Sciences Lecture Series and Conference Department of Mathematical Sciences The Johns Hopkins University Baltimore, Maryland 21218 PROFESSOR ROBERT C. THOMPSON University of California, Santa Barbara will lecture on MATRIX SPECTRAL INEQUALITIES June 20-24, 1988 The 1988 Johns Hopkins Mathematical Sciences Lecture Series and Con- ference will be held during the week of June 20-24, 1988. The principal speaker will be Professor Robert C. Thompson of the University of Califor- nia at Santa Barbara. Professor Thompson's lectures will focus on inequal- ities for eigenvalues, singular values, and invariant factors. Applica- tions in control theory and functional analysis will be mentioned. Professor Thompson will give ten lectures, two each day, on topics such as: eigenvalues of a sum of Hermitian matrices; eigenvalues of a product of unitary matrices; eigenvalues and the exponential function; eigenvalues and the Schubert calculus; invariant factors of matrix pro- ducts and sums; invariant factors, eigenvalues, and representation theory; quaternions and invariant factors; and other related topics. Useful background for the lectures is in Chapter II of Gohberg & Krein's Introduction to the Theory of Linear Nonselfadjoint Operators, American Mathematical Society Translations, Vol. 18, 1969. The lecture series and conference are co-sponsored by the Department of Mathematical Sciences and The Johns Hopkins University Press. A mono- graph by Professor Thompson derived from his lectures will be published by the Press in the Johns Hopkins Series in the Mathematical Sciences. An earlier volume in the Series, Matrix Computations by Gene Golub and Charles Van Loan, is well-known to the matrix theory and numerical analysis community. Invited and contributed talks by participants will provide complemen- tary material and variations on the theme of the lecture series. Informal interactions will be encouraged by small group discussions, sessions for presentation and discussion of open problems, and social events. Participants will be selected from applicants from universities, government, and industry. Interested researchers and advanced graduate students are cordially invited to apply to participate. Applications for travel and subsistence funds for participants have been made to several granting agencies. Inexpensive on-campus housing and meals will be available. All participants are invited to contribute a paper related to the theme of the lecture series. These papers have been specially invited by editors of the new SIAM journal Matrix Analysis and Applications. Potential participants are urged to contact the organizers now in order to receive first priority for further information as it becomes available. Electronic mail is particularly convenient for this purpose. Professor Roger A. Horn or Professor Edward R. Scheinerman Department of Mathematical Sciences, The Johns Hopkins University, Baltimore, Md. 21218 E-mail: MSC_HRAH@JHUVMS (Horn) or MSC_WERS@JHUNIX (Scheinerman) Applications to participate in the Series should be made in writing to either of the organizers and should include a curriculum vitae and a brief statement about one's background and interest in matrix analysis/linear algebra if this is not already evident in the vitae. Please include a complete mailing address, telephone number, and E-mail address, if available. Graduate students should have a letter of recommendation sent from their major professor. All accepted applicants will receive a form to request financial support, but there is no assurance that support will be available. Applications are welcome now, and must be received no later than April 8, 1988 to ensure consideration for on-campus housing and financial support. ------------------------------ Date: Mon, 14 Sep 87 20:08:51 cdt From: dongarra@anl-mcs.ARPA (Jack Dongarra) To: na.dis@score.stanford.edu Subject: Bischof Awarded Wilkinson Fellowship in Computational Mathematics Wilkinson Fellowship in Computational Mathematics We are pleased to announce the winner of the James H.

Does anyone have a canned vector-radix 2D FFT code which inputs a 2D array, or matrix and outputs the 2D FFT? This is done by (decimating) splitting in the 2D directions. See Blahut pp. 242-243 (Fast Algorithms for Digital Signal Processing) and Rivard, G.E. "Direct fast Fourier transform of bivariate functions." IEEE Trans. Acoust. Speech Signal Proc., vol. ASSP-25, no. 3, pp. 250--252, June 1977. Thanks a lot. I guess I could code it up myself, but I'm in a big hurry trying to finish up my dissertation. You know how that goes. In any case, I would really appreciate it if someone could either send me the code, or point to where I can get it. I will fully acknowledge the origin of the code and everything. Thanks, Clare Chu chu@amvax.tn.cornell.edu ------------------------------ Date: Fri, 18 Sep 87 11:13:10 CDT From: dongarra%dasher@anl-mcs.arpa (Jack Dongarra) To: na.dis@score.stanford.edu Subject: Alliant User's Meeting The Alliant Users' Society, ALLUS, is holding its annual meeting October 28 to 30, 1987 at the Royal Sonesta Hotel, New Orleans.

This book is a must for those of you who are totally unfamiliar with multigrid or are uneasy about your current perceptions. The last chapter should be read by anyone who is interested in obtaining a good theoretical understanding of multigrid performance. In simple terms, it unifies the algebraic and spectral theories and gives excellent justification for why multigrid works so well. Finally, if you're thinking about introducing multigrid into the classroom, you should consider this book as a possible supplemental text or resource. The tutorial is fairly short (about 90 pages) with lots of informative graphs and illustrations. Best of all, it's cheap: $10.80 for SIAM members, $13.50 otherwise. You can obtain a copy by writing SIAM Customer Service, 117 S. 17th St., 14th Floor, Phila., PA 19103-5052 or by direct purchase at the October SIAM meeting in Denver where the price will be $9.45.

Smith Mathematics and Computer Science Division Argonne National Laboratory The ANSI Fortran Standards subcommittee X3J3 has completed a draft of the next proposed standard, informally known as Fortran 8x, and is presenting it for public review. The public review lasts for four months and is tentatively expected to begin in early October, 1987. At approximately the same time, the Inter- national Standards Organization is reviewing the draft proposed Fortran standard for three months beginning in early November, 1987. The two reviews will thus be completed at roughly the same time in early February, 1988. The Fortran community, in particular the numerical community, is strongly encouraged to review this draft proposed standard. The document is available from Global Engineering Documents and cost $50 (U.S.A) if sent to a U.S. address and $65 to an internation- al address. International orders can be placed at the following address: Global Engineering Documents Incorporated 2625 Hickory St. Santa Ana, CA 92707 Phone Number (from U.S.A): 1-800-854-7179 Phone Number (outside U.S.A): 1-714-540-9870 This document is written in the form of a draft standard and as such is not very readable. More readable descriptions are avail- able and include the following publications. John Reid and Mike Metcalf have a book titled "Fortran 8x Explained", published by Oxford University Press. Their book will be available in No- vember, 1988. The Department of Energy's Language Working Group has written a paper titled "A Review And Analysis of Fortran 8x", edited by B. T. Smith, Mathematics and Computer Science Division, Argonne National Laboratory, 9700 S. Cass Ave., Lemont, Illinois, U.S.A. 60439. This will be available in late October, 1987. This proposed Fortran standard has been influenced by the parti- cipation of several people from the numerical community. These include: George Paul from IBM Yorktown, John Reid from Harwell, Lawrie Schonfelder from the University of Liverpool, and Brian Smith. The new features of particular interest to the numerical community are the array processing facility, the generalized pre- cision facility, the environmental inquiry and floating point manipulation intrinsic functions, internal procedures, new pro- cedure interface mechanisms, and the new program unit called a module which permits the sharing of global data and procedures. I encourage you to carefully consider the proposed standard and to send comments to the Fortran standards subcommittee X3J3 on the good and bad aspects of the draft.
