**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

known.

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 http://web.mit.edu/18.06/ and MIT's OpenCourseWare page

http://ocw.mit.edu 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: gs@math.mit.edu. 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.

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

solved.

**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

http://documents.wolfram.com/applications/anm/ and is free for

classroom use by students and researchers.

More details about the package and Control System Professional Suite

are available at http://www.wolfram.com/products/applications/anm/

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

http://cnls.lanl.gov/networks

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).

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

identification.

Interested students are invited to send their cv, accompagnied with 3 letters

of reference, a summary of their M.Sc thesis and publications to the address

below before May 1st, 2003.

Master/PhD student in Computer science or related field with experience in

parallel programming and scientific computing. Experience with large C/C++

programs and knowledge of MPI is required. Experience with Matlab is a plus.

Position 2 (REQ# 9061), biochemical pathway reconstruction

(Upper Merion, PA). Experiment with

existing algorithms and develop new ones for pathway reconstruction from

expression data. Minimum requirements: Master/PhD student in Numerical

Analysis/Scientific Computing with experience in optimization algorithms,

knowledge of dynamical systems, inverse problems and regularization

techniques. Good programming skills, preferably in Matlab. Knowledge of

biology is not required but is a plus.

Position 3 (REQ# 9063), animation/scientific visualization (RTP, NC).

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

the dynamical system studied. Minimum requirements: Master/PhD student in

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.
