Existence of Vector Bundles and Global Resolutions for Singular Surfaces
We prove two results about vector bundles on singular algebraic surfaces. First, on proper surfaces there are vector bundles of rank two with arbitrarily large second Chern number and fixed determinant. Second, on separated normal surfaces any coherent sheaf is the quotient of a vector bundle. As a consequence, for such surfaces the Quillen K-theory of vector bundles coincides with the Waldhaus...

متن کاملBrill-Noether theory on singular curves and vector bundles on K3 surfaces
Let C be a smooth curve. Let W r d be the Brill-Noether locus of line bundles of degree d and with r + 1 independent sections. W r d has a expected dimension ρ(r, d) = g − (r + 1)(g − d + r). If ρ(r, d) > 0 then Fulton and Lazarsfeld have proved that W r d is connected. We prove that this is still true if C is a singular irreducible curve lying on a regular surface S with −KS generated by globa...
متن کاملStable vector bundles on algebraic surfaces
We prove an existence result for stable vector bundles with arbitrary rank on an algebraic surface, and determine the birational structure of certain moduli space of stable bundles on a rational ruled surface.
متن کاملBlowups of Surfaces and Moduli of Holomorphic Vector Bundles
We examine the moduli of framed holomorphic bundles over the blowup of a complex surface, by studying a filtration induced by the behavior of the bundles on a neighborhood of the exceptional divisor.
