Subject: New Book, Matrix Analysis for Scientists and Engineers

Matrix Analysis for Scientists and Engineers
Alan J. Laub

Matrix Analysis for Scientists and Engineers provides a blend of
undergraduate- and graduate-level topics in matrix theory and linear
algebra that relieves instructors of the burden of reviewing such
material in subsequent courses that depend heavily on the language of
matrices. Consequently, the text provides an often-needed bridge
between undergraduate-level matrix theory and linear algebra and the
level of matrix analysis required for graduate-level study and
research. The text is sufficiently compact that the material can be
taught comfortably in a one-quarter or one-semester course.

Throughout the book, the author emphasizes the concept of matrix
factorization to provide a foundation for a later course in numerical
linear algebra. The author addresses connections to differential and
difference equations as well as to linear system theory and
encourages instructors to augment these examples with other
applications of their own choosing.

Because the tools of matrix analysis are applied on a daily basis to
problems in biology, chemistry, computer science, econometrics,
engineering, mathematics, physics, statistics, and a wide variety of
other fields, the text can serve a rather diverse audience. The book
is primarily intended to be used as a text for senior undergraduate
or beginning graduate students in engineering, the sciences,
mathematics, computer science, or computational science who wish to
be familiar with enough matrix analysis and linear algebra that they
can effectively use the tools and ideas of these fundamental subjects
in a variety of applications. However, individual engineers or
scientists who need a concise reference or a text for self-study will
also find this book useful.

Prerequisites for using this text are knowledge of calculus and some
previous exposure to matrices and linear algebra, including, for
example, a basic knowledge of determinants, singularity of matrices,
eigenvalues and eigenvectors, and positive definite matrices. There
are exercises at the end of each chapter.

Subject: Workshop in Marseille on Tensor Decompositions and Applications

CIRM, Luminy, Marseille, France

August 29 - September 2, 2005

Organized in cooperation with
the Society for Industrial and Applied Mathematics (SIAM)
and the Centre National de la Recherche Scientifique (CNRS)

Preregistration deadline: May 8, 2005


This workshop is devoted to the study of tensor decompositions. Though
higher-order tensor (also known as multidimensional, multi-way, or n-way
array) decompositions have been around for many years, the door is now
opening on greater mathematical understanding and new applications. This
topic has been the domain of researchers in psychometrics and
chemometrics since the seventies, resulting in, e.g., new methods for
factor analysis. More recently, tensors have found their way to signal
processing via the use of high-order statistics, joint matrix techniques
and applications in telecommunications. Other applications include
complexity theory, (blind) system identification, biomedical
engineering, numerical analysis, and data mining, among others.

The workshop will bring together researchers investigating tensor
decompositions and specialists in scientific computing, linear algebra,
algebraic geometry, and applications. The workshop will feature a series
of invited talks by leading experts, contributed presentations on
specific problems, and group discussions. Tutorials will be provided for
researchers who are new in the field. The goal of the workshop is
further to deepen the theoretical understanding of multilinear algebra,
develop reliable numerical algorithms and tackle new applications.

Specific issues to be addressed include:

* Large-scale problems
* Topological properties of tensor spaces
* Exact or approximate tensor decompositions
* Mathematical properties of tensor decompositions
* Computing using tensor decompositions
* Harmonic analysis
* Independent component analysis
* Applications in wireless communications
* Diagnostics in data analysis
