  • Perturbation analysis of eigenvalues of polynomial matrices smoothly depending on parameters 

    García Planas, María Isabel; Tarragona Romero, Sonia (Wseas Press, 2011-07)
    Part of book or chapter of book
    Open Access
    Let P(¸) = Pk i=0 ¸iAi(p) be a family of monic polyomial matrices smoothly dependent on a vector of real parameters p = (p1; : : : ; pn). In this work we study behavior of a multiple eigenvalue of the monic polynomial family P(¸).
  • Versal deformations in orbit spaces 

    Puerta Sales, Ferran; Puerta Coll, Xavier; Tarragona Romero, Sonia (2003)
    Article
    Open Access
    Given an orbit space $M/\Gamma$ and an equivalence relation defined in it by means of the action of a group $G$, we obtain a miniversal deformation of an orbit through a miniversal deformation in $M$ with regard to a ...
