Subject: SIAM Outreach Membership

The SIAM Board of Trustees has approved a proposal to provide an
affordable membership option for individuals who live and work in
developing countries (as identified by the World Bank). This new
category of membership, called "outreach membership," was created to
help make SIAM products and services accessible to a wider and more
global group of applied and computational mathematicians. This is a
great alternative for individuals in developing countries who cannot
afford the full SIAM dues. For just $25 per year, eligible
individuals receive a slightly reduced set of benefits.

Outreach Members receive all print issues of SIAM News and
electronic-only access to SIAM Review. They can join any of the SIAM
Activity Groups at $10 per group, are entitled to 20% off list prices
on all SIAM books, and receive member discounted registration at SIAM
sponsored meetings. No additional journal subscriptions at membership
rates are available as part of the Outreach Membership.

The Outreach Membership application (secure) form can be found at

Subject: SPEEDUP Workshop

27th SPEEDUP Workshop
Scientific Data Management and Understanding in Computational Science
Hotel Cadro Panoramica
March 16 - 17, 2000

Integrated solutions to computational science problems often require not
only large processing power, but in general also efficient methods and
techniques to store, manage, retrieve, analyze and discover the
knowledge contained in the often huge amounts of data generated in
experiments and computer-based modeling and simulation processes.

This workshop will demonstrate established approaches with examples of
scientific and industrial relevance, but also raise the question whether
these approaches will be sufficient in the future to cope with the
quickly growing complexity of data. Will there be completely new
methods emerging? What can we learn from the experiences gained with
very large data-bases in business computing?

The 27th SPEEDUP Workshop is intended to bring together members of
academic institutions, private enterprises and government who are
interested to obtain an overview of the state-of-the-art in scientific
data processing and to learn about new methods in management of, and
knowledge discovery in, very large amounts of scientific data generated in
computational science modeling and simulation processes.

Topics will include, but will not be limited to the discussion of trends in
Data management and repository organization
Data retrieval techniques
Statistical data analysis
Scientific visualization
Agent technologies for intelligent post-processing
Data warehouses
Data mining

Symposium on
Trends in Nonlinear Analysis - TiNA 2000
Theory, Modelling and Computation
October 8 to 12, 2000


The understanding of nonlinear phenomena has become a central theme
in applied mathematics. The aim of this conference is to discuss
the challenges applied nonlinear analysis has to face given the
increased diversity of scientific problems, and that they are seen
from various points of view.

- In which direction should the classical techniques be developed
- How do new available technologies, particularly concerning the
modern computer, influence the development of our research area?
- Which are the major trends in applied analysis?

Distinguished researchers from different fields will give their
perspectives on these questions.

The conference will close with a reception to celebrate
Willi Jaeger's birthday.

Subject: Workshop on Computer Algebra in Scientific Computing

The Third International Workshop on Computer Algebra
in Scientific Computing
October 5 - 9,2000
Samarkand, Uzbekistan

The methods of Scientific Computing play an important role in research
and engineering applications in the field of the natural and
engineering sciences.

The importance of computer algebra methods and computer algebra systems
for scientific computing has increased considerably in recent times.
During the last decade, a new generation of general-purpose
computer algebra systems such as Mathematica, Maple, MuPAD, Reduce and
Axiom have been developed, which enable the user to solve the following
three important tasks within a uniform framework of the same system:

symbolic manipulations
numerical computations

A further development of such systems, including their adaptation to
parallel environments, puts them at the forefront in scientific computing
and enables the practical solution of many complex applied problems in the
domains of natural sciences and engineering knowledge.

Topics for CASC unites many important questions and methods of
Scientific Computing and the application of computer algebra, like

- computer algebra and approximate computations
- numerical simulation using computer algebra systems
- parallel symbolic-numeric computation
- problem-solving environments
- symbolic-numeric interface
- Internet accessible symbolic and numeric computation
- construction of approximate solutions of ordinary differential
equations and dynamical systems
- symbolic-numeric methods for differential-algebraic equations
- computer algebra analysis of partial differential equations
- algebraic methods for nonlinear polynomial equations and inequalities
- algorithmic and complexity considerations in computer algebra
- applications in the natural sciences

The workshop is intended to provide a forum for researchers and
engineers in the fields of mathematics, informatics, numerical analysis,
etc. An important goal of the workshop is to unite all these specialists
for the purpose of an efficient solution of many current questions and
problems in advanced Scientific Computing.

Subject: Special Issue of Linear Algebra and its Applications

Special Issue of Linear Algebra and its Applications on
Linear Algebra Methods in Representation Theory

In the last three decades in the representation theory of finite-dimensional
algebras over a field or even of more general algebraic structures several new
methods have emerged, including combinatorial, homological, categorical and
geometric aspects. One underlying aspect is the input from Linear Algebra in
a wider sense.

One basic problem in the representation theory is the classification of
indecomposable objects in some Krull-Remak-Schmidt category, or in linear
algebra terminology normal forms of indecomposable matrices. In case there
exists (up to isomorphism) only finitely many such indecomposable objects
(finite type) much more information is available and progress has been made
in case this classification depends only on one-parameter families of
indecomposable objects (tame type). In the remaining case which is usually
called the wild case, there is only scattered information available.

Due to a vast number of internal questions but also problems arising in
applications such as perturbation and control theory the wild case should
be treated seriously.

In the last thirty years the area of representation theory has been extending
in several directions. We want to take this opportunity to devote a special
issue on the Linear Algebra aspects. A preliminary list of topics would

Representations of quivers
Representations of posets and BOCS's
Normal forms of matrices with additional structure
Involutive algebras and their representation theory
Hall algebras
Applications to numerical linear algebra

This is a sample, but not an exclusive list of topics. If there is doubt
about suitability of a particular paper, please contact one of the editors
of the special issue.

Please submit three (3) hard copies to one of the special issue
editors listed below. The format should follow the instructions given

Subject: Special Issue of Linear Algebra and its Applications


CALL FOR PAPERS: Fourth Special Issue on Linear Systems and Control.

In the past, LAA has published three special issues devoted to
the field of Linear Systems and Control: 1983 (vol. 50), 1989
(vols. 122-124) and 1994 (vols. 203-204). More than six years
after the publication of the last special issue, it is time to
take stock of recent and current interactions between Linear
Algebra and Systems Theory.

The cross fertilization between these two fields has been very
fruitful in the past. While linear algebraic methods have been
instrumental for much of the development of linear systems
theory, many system theoretic concepts and constructions are now
part of the body of linear algebra. Today systems theory is a
place where methods from many different parts of mathematics are
combined. As a result linear systems theory has become a rich
source of linear algebraic problems. More recently, new
paradigms, new problems and areas of application have appeared
on the scene: the behavioural approach, coding theory, distance
problems and parameter uncertainty, the dynamic systems approach to=20
algorithms, computational complexity issues in systems theory and
discrete event systems.

These important subject areas have enriched linear systems theory
and will influence the future development of linear algebra, too.
We hope that the upcoming issue will further this process and we
encourage all authors working in these areas to submit their

As in previous issues, this one will be open for all papers with
significant new results in Systems and Control Theory where
either linear algebraic methods play an important role or new
tools and problems of linear algebraic nature are presented.
Also survey papers are very welcome which illustrate specific
areas where the interaction of Systems Theory and Linear Algebra
has been particularly successful. Papers must meet the
publication standards of Linear Algebra and Its Applications and
will be refereed in the usual way.

Areas and topics of interest for this special issue include:

- Structure theory of linear systems and system families
- Stability theory
- Distance problems and analysis of uncertain systems
- Methods of robust control
- Approximation and interpolation problems arising in systems theory
- Geometric control theory and geometry of linear systems
- Linear behaviors
- Multidimensional systems and systems over rings
- Module theoretic techniques in system theory
- Coding theory with connections to systems theory
- Algorithms for linear systems
- Numerical issues in linear systems theory
- Computational complexity in linear algebra and systems theory
- Discrete event systems

The deadline for submission of papers is 31 December 2000, and
the special issue is expected to be published in the first half
of 2002. Papers should be sent to any of its special editors:
