A geometric approach to the Carlson problem
Compta Creus, Albert; Ferrer Llop, Josep (Society for Industrial and Applied Mathematics (Filadèlfia), 2000)
Article
Accés obertThe 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 ... -
Bifurcation diagram for saddle/source bimodal linear dynamical systems

Article
Accés obertWe continue the study of the structural stability and the bifurcations of planar bimodal linear dynamical systems (BLDS) (that is, systems consisting of two linear dynamics acting on each side of a straight line, assuming ... -
Bifurcation diagram of Saddle/Spiral bimodal linear systems
Ferrer Llop, Josep; Peña Carrera, Marta; Susín Sánchez, Antonio (2017-01-01)
Article
Accés obertWe complete the study of the bifurcations of saddle/spiral bimodal linear systems, depending on the respective traces T and t: one 2-codimensional bifurcation; four kinds of 1-codimensional bifurcations. We stratify the ... -
Brunovsky local form of a holomorphic family of pair of matrices

Classi fication of monogenic invariant subspaces and uniparametric linear control systems
Compta Creus, Albert; Ferrer Llop, Josep (2012-12)
Report de recerca
Accés obertThe classification of the invariant subspaces of an endomorphism has been an open problem for a long time, and it is a ”wild” problem in the general case. Here we obtain a full classification for the monogenic ones. Some ... -
