摘要
In this paper we compute the automorphism group of the curves X a,b,n,s and Y n,s introduced in Tafazolian et al. [27] as new examples of maximal curves which cannot be covered by the Hermitian curve. They arise as subcovers of the first generalized GK curve (GGS curve). As a result, anew characterization of the GK curve, as a member of this family, is obtained. (c) 2024 Elsevier Inc.
