      Hopf-Like Bifurcations in Planar Piecewise Linear Systems  [Article]

      Freire Macías, Emilio; Ponce Núñez, Enrique; Torres Peral, Francisco (Universitat Autònoma de Barcelona, Servei de Publicacions, 1997)
      Continuous planar piecewise linear systems with two linear zones are considered. Due to their low differentiability specific techniques of analysis must be developed. Several bifurcations giving rise to limit cycles are ...

      Hopf bifurcation from infinity for planar control systems  [Article]

      Llibre Saló, Jaume; Ponce Núñez, Enrique (Universidad Autónoma de Barcelona. Departamento de Matemáticas, 1997)
      Symmetric piecewise linear bi-dimensional systems are very common in control engineering. They constitute a class of non-differentiable vector fields for which classical Hopf bifurcation theorems are not applicable. For ...

      On the Takens-Bogdanov Bifurcation in the Chua’s Equation  [Article]

      Algaba Durán, Antonio; Freire Macías, Emilio; Gamero Gutiérrez, Estanislao; Rodriguez Luis, Alejandro José (Institute of Electronics, Information and Communication Engineers, 1999)
      The analysis of the Takens-Bogdanov bifurcation of the equilibrium at the origin in the Chua’s equation with a cubic nonlinearity is carried out. The local analysis provides, in first approximation, different bifurcation ...

      On Pták's generalization of Hankel operators  [Article]

      Hernández Mancera, Carmen; Paúl Escolano, Pedro José (Springer, 2001)
      In 1997 Pták defined generalized Hankel operators as follows: Given two contractions T1 ∈ B(H1) and T2 ∈ B(H2), an operator X: H1 → H2 is said to be a generalized Hankel operator if T2X = XT ∗ 1 and X satisfies a ...

      Partial cooperation and convex sets  [Article]

      Romero García, José Enrique; López Vázquez, Jorge Jesús (Institut d'Estadística de Catalunya, 2003)
      We consider games of transferable utility, those that deal with partial cooperation situations, made up of coalition systems, in which every unit coalition is feasible and every coalition of players can be expressed as a ...

      Cooperative games under augmenting systems  [Article]

      Bilbao Arrese, Jesús Mario (Society for Industrial and Applied Mathematics, 2003)
      The goal of this paper is to develop a theoretical framework inorder to analyze cooperative games inwhic h only certaincoalition s are allowed to form. We will axiomatize the structure of such allowable coalitions using ...

      Fixed points and boundary behaviour of the Koenigs function  [Article]

      Díaz Madrigal, Santiago; Contreras Márquez, Manuel Domingo; Pommerenke, Christian (2004)
      We analyze the relationship between the fixed points of different iterates of an analytic self-map of the unit disk. We show that, in general, a boundary fixed point of such a function is not a fixed point of its iterates. ...

      The Postprocessed Mixed Finite-Element Method for the Navier--Stokes Equations  [Article]

      Ayuso, Blanca; García Archilla, Juan Bosco; Novo, Julia (Society for Industrial and Applied Mathematics, 2005)
      A postprocessing technique for mixed finite-element methods for the incompressible Navier–Stokes equations is studied. The technique was earlier developed for spectral and standard finite-element methods for dissipative ...
