Highly tempering infinite matrices
(Springer Milan, 2017-02)
In this short note, it is proved the existence of in nite matrices that
not only preserve convergence and limits of sequences but also convert every mem-

Singular perturbations of Blaschke products and connectivity of Fatou components
(American Institute of Mathematical Sciences (AIMS), 2017)
The goal of this paper is to study the family of singular perturbations of Blaschke products given by Ba,λ(z)=z3z−a1−a¯z+λz2. We focus on the study of these rational maps for parameters a in the punctured disk D∗ and |λ| ...
