**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.
