Divisors and harmonic morphisms on metric graphs of pseudocompact type
Benjamin Mascuch, Montserrat Teixidor i Bigas
A metric graph is of pseudocompact type if identifying parallel edges produces a tree. We give a constructive proof that, for such graphs, divisorial -gonality is equivalent to…
Higher order Petri Loci
Montserrat Teixidor I Bigas
Denote by the subset of the moduli space of curves of genus g consisting of those curves that have a linear series of degree d and dimension r for which…
Brill-Noether loci
Montserrat Teixidor i Bigas
Brill-Noether loci are those subsets of the moduli space determined by the existence of a linear series of degree and dimension . By…
Successive extensions of vector bundles on curves
Montserrat Teixidor i Bigas
We show that on a generic curve, a bundle obtained by successive extensions is stable. We compute the dimension of the set of such extensions. We use degeneration methods specializ…
Brill-Noether loci with ramification at two points
Montserrat Teixidor i Bigas
We prove the injectivity of the Petri map for linear series on a general curve with given ramification at two generic points. We also describe the components of such a set of linea…
Coherent systems on the projective line
P. E. Newstead, Montserrat Teixidor i Bigas
It is well known that there are no stable bundles of rank greater than 1 on the projective line. In this paper, our main purpose is to study the existence problem for stable cohere…
