Discrete Melnikov functions / Gasull, Armengol (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Valls, Clàudia 1973- (Universidade de Lisboa. Instituto Superior Técnico. Departamento de Matemàtica)
We consider non-autonomous N-periodic discrete dynamical systems of the form (Formula presented. ) having when (Formula presented. ) an open continuum of initial conditions such that the corresponding sequences are N-periodic. [...]

On the periods of a continuous self-map on a graph / Guirao, Juan Luis Garcia (Universidad Politécnica de Cartagena. Departamento de Matemática Aplicada y Estadística) ; Llibre, Jaume (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
Let G be a graph and f be a continuous self-map on G. We present new and known results (from another point of view) on the periods of the periodic orbits of f using mainly the action of f on its homology, or the shape of the graph G.

Parrondo's dynamic paradox for the stability of non-hyperbolic fixed points / Cimà, Anna (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Gasull, Armengol (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Mañosa Fernández, Víctor 1971- (Universitat Politècnica de Catalunya. Departament de Matemàtiques)
We show that for periodic non-autonomous discrete dynamical systems, even when a common fixed point for each of the autonomous associated dynamical systems is repeller, this fixed point can became a local attractor for the whole system, giving rise to a Parrondo's dynamic type paradox.

A note on the equilibria of an economic model with local competition ''à la Cournot'' / Guirao, Juan Luis Garcia (Universidad Politécnica de Cartagena. Departamento de Matemática Aplicada y Estadística) ; López, Miguel Angel (Universidad de Castilla-La Mancha. Departamento de Matemáticas) ; Llibre, Jaume (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Martínez, Raquel (Universidad de Castilla-La Mancha. Departamento de Matemáticas)
Guirao and Rubio (2010) [12] introduce an economic model, which generalizes the classical duopoly of Cournot type, where the competitors are located around a circle or a line and each firm competes ''à la Cournot'' with its right and left neighboring. [...]

Parabolic curves for diffeomorphisms in C2 / Brochero Martínez, F. E. (Universidade Federal de Minas Gerais (Belo Horizonte, Brasil). Departamento de Matemática) ; Cano Torres, Felipe (Universidad de Valladolid. Departamento de Algebra, Análisis Matemático, Geometría y Topología) ; López-Hernanz, L. (Universidad de Valladolid. Departamento de Algebra, Análisis Matemático, Geometría y Topología)
We give a simple proof of the existence of parabolic curves for diffeomorphisms in (C 2 , 0) tangent to the identity with isolated fixed point.
