Subject: Numerical Analysis Question
I am looking for an answer to the following question.
Let p(x) = x^{n} + a_{n-1} x^{n-1} + ... + a_{0} be a nomic polynomial
in the complex plan. Let r_{1},r_{2}, ..., r_{m} are all the distinct
roots of p(x). Let d be the smallest distance between the m roots. The
question is if it is possible to estimate d or give a "good" lower bound
ONLY by the coefficients of p(x), a_{n-1},...., a_{0}.
Thank you very much for response.

I agree with Arne. An interactive forum along the lines of the
Usenet newsgroup sci.math.num-analysis would be more productive.
In fact, I think NA Digest and sci.math.num-analysis would
benefit greatly from each other. I know that some mailing lists
are automatically gated into the appropriate newsgroup. Maybe
that could be done in the case of NA Digest. I, for one, would
welcome the change.
Just look how long it's taken to get these three related messages
to the list. In a newsgroup, it's not uncommon for a thread to
generate the same reponse in a matter of hours.

Subject: Eigenvalues of a Toeplitz matrix
I have a 2000x2000 symmetric Toeplitz matrix that needs to be inverted
and the eigenvalues and eigenvectors calculated.
Does anyone know the existence of subroutines that calculate the inverse,
eigenvalues and eigenvectors by taking advantage of the Toeplitz
structure of the matrix?
Do Linpack and/or Lapack have such routines?
Any comments will be appreciated.
Thanks in advance.

Subject: A Matrix Eigenvalue Problem Re: NA Digest, V. 94, # 8
On Wed, 16 Feb 94 09:25 CST, Richard Luczak asked
in NA Digest, V. 94, # 8:
> Let A be a tridiagonal matrix of the form
> -2 2
> 1 -2 1
> . . .
> 1 -2 1
> 2 -2
> What is the formula for all eigenvalues of matrix A?
Let A be n by n with n > 1.
The following is a conjecture, verified only for n=2, n=5 and n=32.
Eigenvector j (not normalized) has the components
cos(i j Pi/(n-1)),
where 0 <= j < n
0 <= i < n.
Arbitrarily picking the first row of A, we have the Eigenvalues
2(cos(j Pi/(n-1)) - 1).
They are in descending order for increasing j. The largest Eigenvalue
is 0, the smallest is -4, independent of n.

Subject: Mathematics Modeling Workshop for Graduate Students at Claremont
THE CLAREMONT COLLEGES
Mathematics Modeling Workshop
for Graduate Students
June 6-14,1994
The Claremont Colleges will host this Workshop as a continuation of the IMA
Summer Program in Mathematical Modeling held August, 1992, and the
Workshop held at Claremont in 1993. See SIAM News, Nov., 1993,
for a description of the latter Workshop. Funding has been
provided by the National Security Agency. The goals are the same as
previously:
(1) To expose 30 mathematics and statistics graduate students
to the excitement of approaching real world problems.
(2) To introduce students to the team approach to problem solving.
In the Workshop the students will be divided into six teams to work on
problems brought by experienced modelers. These problems are derived
from industry or applied science, and require new a fresh insight for
their definition and solution. The problem presenters are being
recruited and their names will be released subsequently.
Note: During June 1-4 an International Conference on Differential
Equations and Applications to Biology and Industry will be held in
Claremont. This Conference pays tribute to Stavros Busenberg who died
last year. Main speakers in Industrial Mathematics are Avner Friedman
and John Ockendon. Students accepted to the Workshop may be interested
in attending this Conference (the Industrial Mathematics portion of the
Conference will be June 3-4), and applications to attend both will
be accepted.
Application Procedure. Graduate students in mathematics, applied mathematics,
statistics or operations research can be nominated for this program by a
faculty member by sending a letter of recommendation. The student must
provide a copy of a recent transcript.
The deadline for applications is May 2.
Students will be expected to finance their travel, although some travel
funds may become available for the students attending the Busenberg
conference. The workshop will cover local living expenses for U.S. citizens
and permanent residents.

Subject: Summer Student Internship Program At CSCS
Introduction
This year, the Swiss Scientific Computing Center CSCS-ETH, in
collaboration with other Swiss institutions, will organize a summer
course for undergraduate students in Manno (TI), Switzerland. CSCS'
Summer Student Internship Program (SSIP) is embedded in the Parallel
Computer Architectures Education Laboratory (ParEdLab), part of CSCS'
Section of Research and Development (SeRD).
During the summer break, for a duration of thirteen weeks between July
and October, up to eight students will be taught basic skills in
programming Distributed Memory Parallel Processors (DMPPs). Each
student is also expected to complete a small research project. The
topics for these projects will deal with today's well-known
programming problems of DMPPs, e.g. development of programming tools,
new algorithms, and scientific applications for such machines.
Student profile
Students participating in the summer student internship program should
have good programming knowledge in either C or Fortran, but no advance
knowledge in parallel systems and parallel programming is required.
The internship program is mainly targeted for Computer Science and
Electrical Engineering students, but also students from other, more
application-oriented fields, e.g. Mechanical Engineering or Material
Sciences, as well as from Mathematics and Physics, can and should
apply. Candidates should have completed their Bachelor of Science
degree, or, in Europe, have passed their intermediate exams at the
university level.
Program
The course will commence on July 18, and end on October 14, 1994. It
will start with a two week introduction to parallel distributed
systems, covering both hardware/system issues and programming of
DMPPs. The lessons will also include exercises on the platform to be
used by the students later on for their own ten-week project.
Each student will give two oral presentations on her/his project --
one intermediate presentation after 5 weeks, and a final presentation
after the project's completion. Each student must summarize her/his
achievements in a final technical report before the SSIP completes.
Advisory scheme
Each student will be assigned an advisor who will assist throughout
her/his stay at CSCS. Each advisor will supervise not more than two
projects.
Infrastructure
CSCS will provide all technical infrastructure, e.g. office space,
workstations and parallel distributed development platforms, such as a
Cenju system supplied by NEC as part of the Joint CSCS-ETH/NEC
Collaboration in Parallel Processing, a Meiko CS-1/860, as well as a a
Hewlett-Packard and Sun workstation clusters.
Financial considerations
CSCS will cover local expenses of all students participating in the
summer student internship program. Support for travel costs is
available.
Projects
A wide range of project topics, from the implementation of development
tool components to the development of parallel applications using High
Performance Fortran (HPF) and other modern programming paradigms, is
available. A partial list of the project topics will be supplied with
the application materials.
Application process
You can request application materials by sending an e-mail to Will
Sawyer, sawyer@cscs.ch, with subject line "SSIP'94 application
request". Complete instructions will be supplied. The deadline for
requesting application materials is March 31, 1994. Completed
applications must be received by April 15, 1994 for consideration.

CONTRIBUTED PAPERS
As an experiment, this meeting has been organized so that the
presentation of contributed papers will be a dialogue rather than
a monologue. Each paper may be presented in three forms: in a
proceedings volume, as a poster display, and as part of a 2-hour
"common interest" discussion session. We expect most of the
contributed papers to be presented in all three forms, though this
is not required. The program contains details. The deadline for
proceedings papers is MARCH 7, 1994.

Subject: Workshop on Domain-based Parallelism And Problem Decomposition Methods
Workshop on DOMAIN-BASED PARALLELISM AND PROBLEM DECOMPOSITION
METHODS IN COMPUTATIONAL SCIENCE AND ENGINEERING
On April 25 and 26, 1994, the University of Minnesota
Supercomputer Institute will host a Workshop on Domain-Based
Parallelism and Problem Decomposition Methods in Computational
Science and Engineering, organized in cooperation with the SIAM
Activity Group on Supercomputing and the Army High Performance
Computing Research Center. The workshop will bring together
researchers from many scientific and engineering disciplines who
exploit `problem decomposition techniques" in various continuous
or discrete senses to develop parallel algorithms. The invited
speakers will take a broad perspective suitable for an
interdisciplinary audience of engineers, physical scientists, and

Subject: Interpolation problem
Suppose you were given, for each point of a square grid, the value
of a function f(x, y), together with {\partial f}/{\partial x} and
{\partial f}/{\partial y}, but no higher order derivatives. How would
you interpolate in this data? (I note that the data overdetermines a
cubic element, but leaves a quartic element underdetermined.)
Any pointers very welcome.

Subject: Book on Numerical Solution of Ordinary Differential Equations Available
The book
NUMERICAL SOLUTION OF ORDINARY DIFFERENTIAL EQUATIONS
Lawrence F. Shampine
ISBN 0-412-05151-6
is now available from the publisher, Chapman & Hall, 29 West
35th Street, New York, NY 10001, (212) 244-3336.
From the preface: "This book is an introduction to the numerical
solution of the initial value problem for a system of ordinary
differential equations (ODEs). ... Chapter 1 provides a sense of
what kinds of problems can be solved numerically and describes how
typical problems can be formulated in a way that permits their
solution with standard codes. ... Chapter 2 explains some of the
limitations of numerical methods. ... Chapter 3 is devoted to the
computational problem and associated software issues. Chapters 4
through 8 derive the basic numerical methods, prove their convergence,
study their stability, and consider how to implement them effectively.
By narrowing the focus of the book to the most important methods, it
is possible to consider them rather carefully and still make minimal
demands on the mathematical and computational background of the reader.
... The book presents a perspective of the numerical solution of
ordinary differential equations that results from some two decades of
research and development by the author in both universities and
scientific laboratories. ... "
