Subject: Generalized Eigenvalue Problem

I am making an inquiry about the following generalized
eigenvalue problem

lambda^2 + lambda [A] + [B]=0

where [A] and [B] are n by n matrices.

If you have knowledge on this topic, please tell me where
I can find out detailed information.

Thanks for your time.

Preliminary Announcement
MATHEMATICAL MODELLING AND COMPUTATIONAL METHODS
"MODELLING 94"

Prague, Czech Republic
August 29 -- September 2, 1994

International Symposium organized by

Institute of Computer Science AS CR, Prague
Mathematical Institute AS CR, Prague
Faculty of Mathematics and Physics, Charles University, Prague
Faculty of Nuclear Sciences and Physical Engineering,
Czech Technical University, Prague
Faculty of Applied Sciences, University of West Bohemia, Pilsen
Orthopaedic Clinic of the 3rd Medical Faculty,
Charles University, Prague

MODELLING 94 will provide an interdisciplinary forum in which
researchers in the field of mathematical modelling and
computational mathematics can present results and exchange ideas
and information. The symposium will cover a broad range of
topics relevant to the field of mathematical modelling in
science. These topics will include the following:

* Mathematical modelling and simulation in science and
technology
* Computational methods for the solution of corresponding model
problems
* Methods of numerical algebra and analysis
* Expert systems in science
* Visualization techniques for pre- and post-processing

The MODELLING 94 programme will include invited lectures, short
communications and posters. Papers presented at the symposium
will be published in the Proceedings.
