Title
A new family of maximal curves.
Abstract
In this article we construct for any prime power q and odd n >= 5, a new F-q2n-maximal curve X-n. Like the Garcia-Guneri-Stichtenoth maximal curves, our curves generalize the Giulietti-Korchmaros maximal curve, though in a different way. We compute the full automorphism group of X-n, yielding that it has precisely q(q(2) - 1)(q(n) + 1) automorphisms. Further, we show that unless q = 2, the curve X-n is not a Galois subcover of the Hermitian curve. Finally, up to our knowledge, we find new values of the genus spectrum of F-q2n-maximal curves, by considering some Galois subcovers of X-n.
