Abstract

We prove interlacing inequalities for the eigenvalues of the submatrices of (weakly) hyperbolic and gyroscopic quadratic pencils.

This work was partly done while the author stayed at the University of Osijek, under the support of National Foundation for Science, Higher Education and Technological Development of the Republic of Croatia.
