    • Completely decomposable Jacobian varieties in new genera 
      Paulhus, Jennifer; Rojas Rodríguez, Anita (Taylor & Francis, 2017)
      We present a new technique to study Jacobian variety decompositions using subgroups of the automorphism group of the curve and the corresponding intermediate covers. In particular, this new method allows us to produce many ...
    • Group actions on Jacobian varieties 
      Rojas, Anita M. (Universidad Autonoma de Madrid, 2007)
      Consider a finite group G acting on a Riemann surface S, and the associated branched Galois cover πG : S → Y = S/G. We introduce the concept of geometric signature for the action of G, and we show that it captures much ...
    • On large prime actions on Riemann surfaces 
      Reyes Carocca, Sebastián Andrés; Rojas Rodríguez, Anita María (Walter de Gruyter GMBH, 2022)
      In this article, we study compact Riemann surfaces of genus g with an automorphism of prime order g C 1. The main result provides a classification of such surfaces. In addition, we give a description of them as algebraic ...
