Rank four vector bundles without theta divisor over a curve of genus two

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/212403We show that the locus of stable rank four vector bundles without theta divisor over a smooth projective curve of genus two is in canonical bijection with the set of theta-characteristics. We give several descriptions of these bundles and compute the degree of the rational theta map.8 pagesAlgebraic Geometry14H60, 14D20Rank four vector bundles without theta divisor over a curve of genus twotext
