Subject: Seeking Software for Sparse Eigenvalue Problems

Does anyone know about any free software to compute the eigenvalues and
eigenvectors of a real symmetric sparse matrix, e.g. for 5 diagonal
system (for Laplacian operator in 2 dimensions). I am searching for
the possibility of computing the full spectrum and eigenvectors
therefore, it is necessary to compute the spectrum in intervals
in order to save memory allocation.

Subject: Workshop on Bifurcations, Analysis, Numerical Methods, Software

A workshop on


will be organized at the University of Gent, Belgium on June 24 - 25, 1999.

SCOPE of the meeting: It is now widely acknowledged that the
applicability of the results in dynamical systems theory depends
strongly on the existence of good numerical algorithms and
the availability of good software to deal with the examples that
arise in application areas. On the other hand, numerically
obtained results are not particularly interesting when they are
not placed in the correct mathematical framework. We hope that
the discussions in this meeting will contribute to a good
understanding of the relation between analysis and software.

Organizers : W. Govaerts (Gent,B)
D. Roose (Leuven, B)
A. Vanderbauwhede (Gent,B)

About this event:

Computer Algebra or Symbolic Computing is a young field of research inbetween
Computing and Mathematics. Merging both mentalities (one theoretical and the
other closer to the real world) provides a fertilized soil for the growth of
new useful and exciting applications. Although the same kind of tools are in
the background, a broad variety of fields are covered, as the sessions
organized at IMACS-ACA '98 show: Robotics, High Energy Physics, Industry,
Algebra and Geometry, Artificial Intelligence, Education, Biology...
This will be the 5th IMACS-ACA. Previous ones have taken place in
Albuquerque, New Mexico (USA) 1995; Linz (Austria) 1996; Wailea, Maui, Hawaii
(USA) 1997 and Prague (Czech Republic) 1998. The evolution of the number of
talks and attendees indicate a rapidly increasing interest in this particular
Probably the two most important conferences about Computer Algebra nowadays
are the much older ISSAC and IMACS-ACA. IMACS-ACA is getting nearly as many
attendees as ISSAC. Moreover, as far as we know, IMACS-ACA is the only
conference in the world specifically devoted to applications of this field.
In previous years organizations and companies as important as the American
National Science Foundation (NSF) and National Security Agency (NSA), Czech
Ministry of Education, Texas Instruments, Wolfram Research... have sponsored
this conference.

Subject: Conference on Complementarity Problems

An International Conference on Complementarity Problems will be held
in Madison, Wisconsin on June 9 - 12, 1999. The contemporary
applications and algorithms that will be emphasized at the meeting
will reflect the 35 years that have passed since complementarity was
formally introduced and employed as a powerful mathematical model for
a wide spectrum of problems in diverse fields.

The conference is intended to bring together engineers, economists,
industrialists, and academicians from the U.S. and abroad who are
involved in pure, applied, and/or computational research of
complementarity and related problems.

The conference will consist of invited presentations, and is limited
to 100 participants (including the speakers). A refereed volume of
proceedings of the conference will be published. There are three
major themes of the conference: engineering and machine learning
applications, economic and financial applications, and computational
methods. Each theme will be represented by several experts in the
