      The symmetric action on secondary homotopy groups 

      Baues, Hans Joachim; Muro Jiménez, Fernando (The Belgian Mathematical Society, 2008-11)
      We show that the symmetric track groups Sym(n), which are extensions of the symmetric groups Sym(n) associated to the second Stiefel-Whitney class, act as crossed modules on the secondary homotopy groups of a pointed space.

      Thue equations and torsion groups of elliptic curves 

      García Selfa, Irene; Tornero Sánchez, José María (Elsevier, 2009-02)
      A new characterization of rational torsion subgroups of elliptic curves is found, for points of order greater than 4, through the existence of solution for systems of Thue equations.
