    • Generalization of Vélu’s formulae for isogenies between elliptic curves 

      Miret, Josep M. (Josep Maria); Moreno Chiral, Ramiro; Rio, Anna (Universitat Autònoma de Barcelona. Departament de Matemàtiques, 2007)
      Given an elliptic curve E and a finite subgroup G, V ́lu’s formulae concern to a separable isogeny IG : E → E ′ with kernel G. In particular, for a point P ∈ E these formulae express the first elementary symmetric polynomial ...
