Sensitivity of Schur stability of systems of linear difference equations with constant coefficients

In this work, sensitivity of the Schur stability and the ω*-Schur stability of linear difference equation systems with constant coefficients have been investigated, and new results on the sensitivity problem have been given. The results have applied the scalar-linear difference equations with order κ and supported with numerical examples and also compared with the existing ones in the literature. © 2011 Academic Journals.
