A Note on 2 Methods Related to Stability Robustness of Polynomials in a Sector (Relative Stability) - Comment
In this paper, it is shown that the results of the above-mentioned paper arp incorrect for the case of complex coefficients. A counterexample is provided. An alternative approach is presented for the calculation of sector-stability hypersolids in the coefficient space.
