On a F_{q^2}-maximal curve of genus q(q-3)/6
Miriam Abdon, Fernando Torres
We show that a F_{q^2}-maximal curve of genus q(q-3)/6 in characteristic three is either a non-reflexive space curve of degree q+1, or it is uniquely determined up to F_{q^2}-isomo…

On maximal curves and unramified coverings
Rainer Fuhrmann, Arnaldo Garcia, Fernando Torres
We discuss sufficient conditions for a given curve to be covered by a maximal curve with the covering being unramified; it turns out that the given curve itself will be also maxima…
