Moreover, a way to study perturbation effects on the coefficient range is outlined. The results may be used in a preprocessing rejection scheme when testing for robust Schur-stability.en1474-6670200311259262ElsevierConformal mappingReal polynomialsSehur-stabilityStructured perturbationInformatikMathematikJournal Article10.1016/S1474-6670(17)35673-2Other
