A. Aasaraai, Kameleh Nasiri Pirbazari · Applications and Applied Mathematics: An International Journal (AAM) · 2010
The present study is intended to demonstrate that for a descriptor system with matrix pencil there exists a matrix such that matrix and matrix pencil have the same positive and negative eigenvalues. It is also shown that matrix can be calculated as a contour integral. On the other hand, different representations for matrix are introduced.
