Clifford indices for vector bundles on curves
H. Lange, P. E. Newstead
For smooth projective curves the Clifford index is an important invariant which provides a bound for the dimension of the space of sections of a line bundle. This is the first step…
Hodge polynomials and birational types of moduli spaces of coherent systems on elliptic curves
H. Lange, P. E. Newstead
In this paper we consider moduli spaces of coherent systems on an elliptic curve. We compute their Hodge polynomials and determine their birational types in some cases. Moreover we…
Products of Jacobians as Prym-Tyurin varieties
A. Carocca, H. Lange, R. E. Rodriguez +1
Let denote smooth projective curves of genus over an algebraically closed field of characteristic 0 and let denote any integer at least equal to $1…
Prym-Tyurin varieties using self-products of groups
A. Carocca, H. Lange, R. E. Rodriguez +1
Given Prym-Tyurin varieties of exponent with respect to a finite group , a subgroup and a set of rational irreducible representations of satisfying some additional p…
Prym varieties of cyclic coverings
H. Lange, A. Ortega
The Prym map of type (g,n,r) associates to every cyclic covering of degree n of a curve of genus g, ramified at a reduced divisor of degree r, the corresponding Prym variety. We sh…
Prym-Tyurin varieties via Hecke algebras
A. Carocca, H. Lange, R. E. Rodriguez +1
Let denote a finite group and a Galois covering of smooth projective curves with Galois group . For every subgroup of there is a canonical action of the…
