    • Recobrimentos ramificados entre superfícies e dessins d'enfants 

      Panzarin, Karen Regina (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Matemática - PPGM, , 19/03/2012)
      Given closed connected surfaces X and Y, integers n > 0 and d > 2, and for i = 1,..., n partitions (dy)j=i,...,mi of d. The 5-tuple (X, Y, n, d, (dij)) is called the branch datum of a candidate branched covering. Many works ...

    • Recobrimentos ramificados entre superfícies e 2-orbifolds geométricos 

      Rocha, Laurindo Daniel Silva da (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Matemática - PPGM, , 22/10/2014)
      The purpose of this work is to study the realizability problem of branched coverings between closed, connected and orientable surfaces. For each covering, there exists a set of naturally associated data called branch datum ...
