On the Stability Radius of Matrix Polynomials [PDF]

open access: possibleLinear and Multilinear Algebra, 2002
The stability radius of a matrix polynomial P ( λ ) relative to an open region ω of the complex plane and its relation to the numerical range of P ( λ ) are investigated. Using an expression of the stability radius in terms of λ on the boundary of ω and A P ( λ ) m 1 A 2 , a lower bound is obtained.

The stability radius of a semi-Fredholm operator

Integral Equations and Operator Theory, 1985
We prove an asymptotic formula for the stability radius of a semi-Fredholm operator on a Banach space in terms of the reduced minimum modulus. In particular, this gives a new proof of the Fredholm case studied by Forster and Kaashoek [4].
