Inverse Spectral Problems for Linked Vibrating Systems and Structured Matrix Polynomials
Keivan Hassani Monfared, Peter Lancaster
We show that for a given set of distinct real numbers and graphs on nodes, , there are real symmetric $n\times…

On the boundary of the pseudospectrum and its fault points
Lyonell Boulton, Peter Lancaster
The theme of this paper was motivated by the question: How effective are path-following procedures for tracing the pseudospectral boundary? The present study of the mathematical pr…

On Pseudospectra of Matrix Polynomials and their Boundaries
Lyonell Boulton, Peter Lancaster, Panayiotis Psarrakos
In the first part of this paper, the main concern is with smoothness properties of the boundary of the pseudospectrum of a matrix polynomial. In the second part, results are obtain…
