| dc.description.abstract | Sometimes we obtain attractive results when associating facts to simple elements. The goal of this work is to introduce a possible alternative in the study of the dynamics of rational maps. In this study we use the family of maps f(x) = (x^2-a)/(x^2-b), making some associations with the matrix A of its coefficients. Calculating the numerical range W(A), the numerical radii r(A) and br(A), the boundary of the numerical range @W(A), powers and iterations, we found relations very interesting, especially with the entropy of this maps. | en |
