16 p, 431.6 KB Rational parameterizations approach for solving equations in some dynamical systems problems / Gasull, Armengol (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Lázaro, J. Tomás (Universitat Politècnica de Catalunya. Departament de Matemàtiques) ; Torregrosa, Joan (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We show how the use of rational parameterizations facilitates the study of the number of solutions of many systems of equations involving polynomials and square roots of polynomials. We illustrate the effectiveness of this approach, applying it to several problems appearing in the study of some dynamical systems. [...]

26 p, 414.4 KB Dynamical classification of a family of birational maps of C2 via algebraic entropy / Zafar, Sundus (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Cimà, Anna (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
This work dynamically classifies a 9-parametric family of birational maps f: C→ C. From the sequence of the degrees d of the iterates of f, we find the dynamical degree δ(f) of f. We identify when d grows periodically, linearly, quadratically or exponentially. [...]
