Clifford's Theorem for Coherent Systems on surfaces

L. Costa, I. Macías Tarrío, L. Roa-Leguizamón

Let X be a smooth irreducible projective surface. The aim of this paper is to establish a version of Clifford's theorem for coherent systems on X.

A family of maps and a vector field on plane polygons

Maxim Arnold, Lael Costa, Serge Tabachnikov

We study, theoretically and experimentally, a 1-parameter family of transformations and their limiting vector field on the space of plane polygons. These transformations are discre…

Brill-Noether Theory of stable vector bundles on ruled surfaces

L. Costa, I. Macías Tarrío

Let X be a ruled surface over a nonsingular curve C of genus $g \geq 0$ . Let $M_{H} := M_{X, H} (2; c_{1}, c_{2})$ be the moduli space of H-stable rank 2 vector bundles E on X with fixed Chern c…
