Subject: A Matrix Problem

Let F be a Hermitian matrix. Is there always an antisymmetrix matrix A such
that G = exp(-A) F exp(A) is block diagonal with prescribed block sizes,
and the entries of A vanish in the corresponding diagonal blocks?

(Clearly, the answer is yes if there is only one block or if all blocks have
size 1.)

To which extent are G,A uniquely determined by F?
To which extent do G,A depend continuously on F?

Subject: New Edition, Introduction to Linear Algebra

Dear NA Digest readeers:

Here is my announcement about a new edition of Introduction to Linear
Algebra. I am hoping that readers who care about this subject will
encourage math departments to realize what this course can be
(and how important it is). It is often taught by people who
have no direct knowledge of its applications -- they just learned it
as a math subject -- and without help they just offer a course
for pure math majors.

I really think that the undergraduate course is the key to the future
of the subject in all directions. This is the time when departments
decide about courses. I am proud of this new edition and happy if it is

Very best regards, Gil

New Edition: Introduction to Linear Algebra, Gilbert Strang (March 2003)

This is the new Third Edition of Gil Strang's highly popular textbook.
It has 100 Worked Examples to connect the basic ideas of linear algebra
to the applications and exercises. In every direction this book aims to
help students and faculty:

** A new Glossary of key definitions and properties
** Short conceptual questions to review the essential ideas
** A one-page outline: Linear Algebra in a Nutshell
** A new section on Matrices in Engineering
** Videos of the full course (with syllabus and exams) on the web

The web page and MIT's OpenCourseWare page both have all the material we can provide to make this
an outstanding undergraduate course. It can attract students to the whole
range of computational science and mathematics.
We want desk copies to go to faculty who teach linear algebra! The best
contact is directly to: If you could send names/addresses/
email contacts we will ask permission to offer a desk copy.
The publisher is Wellesley-Cambridge Press (ISBN 09614088-98), to maintain
reasonable cost to students. We ask your help to make this new edition widely
known. Thank you.

Below you will find a brief description of a new title published by
Princeton University Press. We hope that you will find this title of
interest to your members and will post our message to your discussion list.

Four Colors Suffice:
How the Map Problem Was Solved

Robin Wilson

On October 23, 1852, Professor Augustus De Morgan wrote a letter to a
colleague, unaware that he was launching one of the most famous mathematical
conundrums in history--one that would confound thousands of puzzlers for
more than a century. This is the amazing story of how the "map problem" was

Subject: A Control Software Package for Mathematica

A New Control Software Package: Advanced Numerical Methods

I am pleased to announce the release of a new control software
package called "Control System Professional - Advanced Numerical Methods".

Advanced Numerical Methods is a new Mathematica application package
that I and my former student Daniil Sarkissian, currently with
Mississippi State University, developed in collaboration with Wolfram
Research. The package is a part of Control System Professional Suite,
which provides an object-oriented environment with symbolic, numeric,
and arbitrary precision tools for modeling, analysis, design, and
simulation of control systems.

Advanced Numerical Methods adds an extensive collection of numerical
algorithms for each problem. Users can select the most appropriate
tool for a given task or have the package choose a suitable method
automatically based on the size of data and the required accuracy.

The implemented algorithms include:

- The Schur and Hessenberg-Schur methods for the Lyapunov and
Sylvester matrix equations
- The Schur, Newton, matrix-sign function, and inverse-free methods
for solving the algebraic Riccati equations
- The block-Hessenberg forms and Cholesky factors of the
controllability and observability Gramians
- The recursive, explicit QR, Schur, and other algorithms for pole
assignment, as well as the projection technique for the partial
pole assignment
- Constrained feedback stabilization using the pole assignment and
Lyapunov algorithms
- The design of the reduced-order state estimator and model reduction
via an extensive library of algorithms
- System identification using the Markov parameters, the subspace
identification method, and the frequency-domain methods
- Algorithms for the generalized matrix eigenvalue problem, the
generalized Schur decomposition, and the ordered Schur and
generalized Schur decompositions

The package is integrated with the Mathematica Help Browser and
includes a 137-page manual. Examples are provided for applications in
the aeronautic, chemical, mechanical and electrical engineering disciplines, and
other fields. The entire documentation is also available online at and is free for
classroom use by students and researchers.

More details about the package and Control System Professional Suite
are available at

Subject: Conference in Sante Fe on Networks: Structure, Dynamics and Function

The Center for Nonlinear Studies at Los Alamos National Laboratory
is pleased to announce its 23rd Annual Conference on

Networks: Structure, Dynamics and Function
May 12 - 16, 2003, Hotel La Fonda, Santa Fe, New Mexico, USA

Our world is a complex mesh of interacting elements, both natural and
man-made. Recent observations suggest that the formation of such complex
networks is not random, but rather follows fundamental organizing principles.
The 2003 CNLS Annual Conference focuses on the search for underlying
principles in the structure, dynamics, and function of complex networks.

The conference will facilitate cross-disciplinary interactions by bringing
together researchers from a diverse set of fields. The emphasis will be
analysis of real-world data from information networks (internet, www, data
networks), biological networks (in proteomics, gene networks, metabolic
networks), social networks (including epidemiological networks) and
infrastructure networks (power grid, transportation networks).

Speakers include:

nonlinear system identification.

The goal of the study is to develop numerical solutions for the identification
of various classes of nonlinear systems, such as Linear parameter varying
systems and composite local linear models. The developments need to focus on
the reliability, efficiency and userfriendliness of the algorithms. The
developed algorithms will be valied in real-life validation studies on
mechatronic macro- and microsystems. The study is embedded in the longterm
tradition of the research center in the field of algorithms and system

Develop tools for
animating dynamical systems such as biochemical pathways or chemistry
kinetics. The animated movies created using these tools should help
demonstrate some of the complex interactions and nonlinear behaviors of

Computer Science, Scientific Computing or related field. Experience with
animation and/or scientific visualization. Knowledge of VRML or Matlab is
a plus.

We are looking for individuals who can successfully integrate
sophisticated mathematics and computer software with biological problems.
We seek someone who has the motivation to solve real-world problems.
Interactions will often be with a larger team composed of other
computational scientists and R&D researchers. Excellent communication
skills are required. Exceptionally talented undergraduate students also
will be considered for all three positions.
