Type of homomorphisms of complex tori
Juliana Coelho
Using determinantal divisors of integral matrices, that is, greatest common divisors of minors of fixed order, we introduce the notion of type of a homomorphism of complex tori…
Characterizing -elliptic stable irreducible curves
Juliana Coelho, Renata Costa
We use admissible covers to characterize irreducible stable curves that are -elliptic, that is, that are limits of smooth curves admiting finite maps of degree- to smooth…
Gonality of curves whose normalizations are one or two copies of
Juliana Coelho
We study the gonality of curves over whose normalization is composed of one or two copies of . In the first case, is a nodal curve with node…
Characterizing gonality for two-component stable curves
Juliana Coelho, Frederico Sercio
It is a well-known result that a stable curve of compact type over having two components is hyperelliptic if and only if both components are hyperelliptic and the poin…
Abel-Prym maps for isotypical components of Jacobians
Juliana Coelho, Kelyane Abreu
Let be a smooth non rational projective curve over the complex field . If is an abelian subvariety of the Jacobian , we consider the Abel-Prym map $φ_A :…
On the gonality of stable curves
Juliana Coelho, Frederico Sercio
In this paper we use admissible covers to investigate the gonality of a stable curve over . If is irreducible, we compare its gonality to that of its normalizat…
