Subject: Deuflhard heads the Konrad Zuse Center

Dear Colleagues,

This is a general letter to reach all those of you
that have not yet received my new address. 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

      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.

From: chu@tcgould.tn.cornell.edu  (Clare Chu)
Subject: Vector-radix 2D FFT code
To: na@score.stanford.edu

Hi. 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

Subject: C Math Library Needed
To: na@score.stanford.edu

I'm looking for a GOOD (IMSL-like)package of math subroutines,
preferably written in C,
and callable from a C program. My main use is solving nonlinear
equations, and the version of IMSL that we have doesn't implement
the homotopy method.
Does anyone know of other packages available ?
Will they make the accountants scream ?
I need stuff that will run under UNIX, on a VAX 11/785.
Please reply by e-mail, and I'll post a summary to the net.

Subject: Briggs Tutorial on Multigrid Available from SIAM
To: na@SCORE.STANFORD.EDU

                     A MULTIGRID TUTORIAL


For those of you who want to get a basic understanding of multigrid concepts
and principles, you should know that SIAM is just about to publish "A Multigrid
Tutorial" by Bill Briggs. 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.

Subject: Announcement of Fortran 8x

    The Public Review Of The Next Draft Proposed Fortran Standard
Begins

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:

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.  Comments should  be  sent

       THE INSTITUTE OF MATHEMATICS AND ITS APPLICATIONS

  Conference on COMPUTATIONAL ORDINARY DIFFERENTIAL EQUATIONS

Imperial College, London                               July 3-7, 1989

                   FIRST CALL FOR PAPERS AND POSTERS

The IMA, jointly with SIAM, is organizing a conference on Computational
Ordinary Differential Equations, to be held at Imperial College, London,
in July 1989.  

The aim of this meeting is to bring together research workers and
practitioners in theory and algorithms for the numerical solution of
ordinary differential equations.  Contributions from workers in applications
areas will be encouraged.  The format of the meeting will be designed to
permit maximum interaction between the participants.  The use of
parallel sessions will be minimized and, if practicable, avoided.

The following are the topics to be covered in the conference:
   (i) Theory and algorithms for the numerical solution of initial and
       boundary value problems in ordinary differential equations, 
       differential algebraic equations and delay equations.
  (ii) Applications areas including the method of lines for partial
       differential equations.
 (iii) Structured and compartmentalized systems.
  (iv) Numerical methods for dynamical systems.
   (v) Parameterized and bifurcation problems.
  (vi) Impact of supercomputers on numerical methods for ordinary
       differential equations.
 (vii) Expert systems and graphics in ordinary differential equations.
(viii) Related topics.

The program will include ``highlighted'' papers, contributed papers
and posters.  The highlighted papers will be of 40 minutes presentation
time, and contributed papers of 20 minutes presentation time.  The
highlighted papers will be selected by the organizing committee
(J. R. Cash, A. R. Curtis, R. England, I. Gladwell and A. Iserles)
on the basis of an extended abstract (1000 words), contributed papers
and posters on the basis of a 300 word abstract.  Abstracts for all
categories should be sent to the IMA and must be received by
December 1, 1988.  Authors will be notified of the committee's decision
during January 1989.

There will be a reduced conference fee for full-time graduate students.

The proceedings of the conference will be published by Oxford University
Press in the IMA Conference Proceedings Series.

Abstracts and other enquiries should be sent to:
  The Secretary and Registrar
  The Institute of Mathematics and its Applications
  Maitland House, Warrior Square
  Southend-on-Sea
  Essex SS1 2JY
  United Kingdom.

Information can also be obtained from J.R. Cash, either by post
at: Department of Mathematics, Imperial College, Queen's Gate, 
London SW7 2BZ, United Kingdom, or electronically, at
NA.CASH @ SCORE.Stanford.Edu.

Subject:  Pascal Graph Algorithms Sought

The following message is from Kathy O'Hara, a member of the Mathematics
Dept. at the University of Iowa.  In sending mail replies, send to her
directly at the University of Iowa, Iowa City, Iowa 52242.   For E_mail
replies, send those to NA.ATKINSON.
             Ken Atkinson

     I'm looking for graph algorithms coded in Pascal.  Specifically, the
graph algorithms that appear in Reingold, Nievergelt, and Deo's
Combinatorial Algorithms.  I am particularly interested in the algorithms
that, given a graph,
     (a)  list all of its cycles
     (b)  finds all maximal cliques
     (c)  tests for planarity
Any information concerning coded versions of these or other graph
algorithms would be appreciated.

Thanks,

Kathy O'Hara
