  • Abstract
    The automorphism groups are determined for the one-point codes C m on the curve over Fq2r defined by yq+y=xqr+1, where r is an odd number. This generalizes Xing´s theorem (see ibid., vol.41, p.1629-35, Nov. 1995) and extends a result of Wesemeyer (see ibid., vol.44, p.630-43, March 1998)to the case of the above curve
