    • A geometric approach to the Carlson problem 

      Compta Creus, Albert; Ferrer Llop, Josep (Society for Industrial and Applied Mathematics (Filadèlfia), 2000)
      Article
      Accés obert
      The possible observability indices of an observable pair of matrices, when supplementary subpairs are prescribed, are characterized when the “quotient” one is nilpotent. The geometric techniques used are also valid in the ...

    • Versal deformations in orbit spaces 

      Puerta Sales, Ferran; Puerta Coll, Xavier; Tarragona Romero, Sonia (2003)
      Article
      Accés obert
      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 ...
