A new preprint on the automorphism group of a family of maximal curves is now available on arXiv here.
It was written by algebra group member Maria Montanucci , Guilherme Tizziotti from Universidade Federal de Uberlândia (UFU), Brazil and Giovanni Zini from University of Modena e Reggio Emilia (Unimore). In the preprint the automorphism group of a family of maximal curves which is not covered by the Hermitian curve is computed. This family is related to the famous GK curve, and in this way a new characterization of this curve (as a member of the family) is obtained.
