Remarks on numerical semigroups
Fernando Torres
We extend results on Weierstrass semigroups at ramified points of double covering of curves to any numerical semigroup whose genus is large enough. As an application we strengthen…
On Weierstrass points and optimal curves
Rainer Fuhrmann, Fernando Torres
We use Weierstrass Point Theory and Frobenius orders to prove the uniqueness (up to isomorphism) of some optimal curves.
Quotient curves of the Deligne-Lusztig curve of Suzuki type
Massimo Giulietti, Gábor Korchmáros, Fernando Torres
Inspired by a recent paper of Garcia, Stichtenoth and Xing [2000, Compositio Math. 120, 137--170], we investigate the quotient curves of the Deligne-Lusztig curve associated to the…
Embedding of a maximal curve in a Hermitian variety
Gabor Korchmaros, Fernando Torres
Let X be a projective geometrically irreducible non-singular algebraic curve defined over a finite field F of order . If the number of F-rational points of X satisfies the Has…
Automatic analysis of Categorical Verbal Fluency for Mild Cognitive Impartment detection: a non-linear language independent approach
Karmele López-De-Ipiña, Unai Martinez de Lizarduy, Nora Barroso +4
Alzheimer's disease (AD) is one the main causes of dementia in the world and the patients develop severe disability and sometime full dependence. In previous stages Mild Cognitive…
On certain N--sheeted coverings and numerical semigroups which cannot be realized as Weierstrass semigroups
Fernando Torres
A curve is said to be of type if it is an --sheeted covering of a curve of genus with at least one totally ramified point. A numerical semigroup is said to…
