摘要:
For Schur polynomials with perturbed coefficients, a lower bound is derived for the radius of the hypersphere in the parameter space, within which the perturbed polynomials retain the Schur property. The result is obtained via the Lyapunov matrix equation and is expressed in terms of the size of the solution lo the equation This enables us to estimate the allowable size of the perturbation simply by solving the equation.
