    • Local convex directions 

      Özgüler, Arif Bülent; Saadaoui, Karim (IEEE, 2001)
      A proof of a strengthened version of the phase growth condition for Hurwitz stable polynomials is given. Based on this result, a necessary and sufficient condition for a polynomial p(s) to be a local convex direction for ...
    • Local convex directions for Hurwitz stable polynomials 

      Özgüler, A. B.; Saadaoui, K. (IEEE, 2002)
      A new condition for a polynomial p(s) to be a local convex direction for a Hurwitz stable polynomial q(s) is derived. The condition is in terms of polynomials associated with the even and odd parts of p(s) and q(s), and ...
