A Gieseker Type Degeneration of Moduli Stacks of Vector Bundles on Curves
نویسنده
چکیده
We construct a new degeneration of the moduli stack of vector bundles over a smooth curve when the curve degenerates to a singular curve which is irreducible with one double point. We prove that the total space of the degeneration is smooth and its special fibre is a divisor with normal crossings. Furthermore, we give a precise description of how the normalization of the special fibre of the degeneration is related to the moduli space of vector bundles over the desingularized curve.

On degeneration of surface in Fitting compactification of moduli of stable vector bundles
The new compactification of moduli scheme of Gieseker-stable vector bundles with the given Hilbert polynomial on a smooth projective polarized surface (S,H), over the field k = k̄ of zero characteristic, is constructed in previous papers of the author. Families of locally free sheaves on the surface S are completed by the locally free sheaves on the surfaces which are certain modifications of S....
متن کاملTwisted Vector Bundles on Pointed Nodal Curves
This paper grew out of an attempt to understand a recent draft of Seshadri ([Se2]) and is meant as a contribution in the quest for a good compactification of the moduli space (or stack) of G-bundles on a nodal curve. We are led by the idea that such a compactification should behave well in families and also under partial normalization of nodal curves. This statement may be reformulated by sayin...
متن کاملModuli of High Rank Vector Bundles over Surfaces
The purpose of this work is to apply the degeneration theory developed in [GL] to study the moduli space of stable vector bundles of arbitrary rank on any smooth algebraic surface (over C). We will show that most of the recent progress in understanding moduli of rank two vector bundles can be carried over to high rank cases. After introducing the notion of stable vector bundles, the first autho...
متن کاملRationality and Poincaré Families for Vector Bundles with Extra Structure on a Curve
Iterated Grassmannian bundles over moduli stacks of vector bundles on a curve are shown to be birational to an affine space times a moduli stack of degree 0 vector bundles, following the method of King and Schofield. Applications include the birational type of some Brill-Noether loci, of moduli schemes for vector bundles with parabolic structure or with level structure and for A. Schmitt’s deco...
متن کاملThe Moduli Stack of Gieseker-sl2-bundles on a Nodal Curve Ii
Let X0 be an irreducible projective nodal curve with only one singular point, and let P0 be a line bundle on X0. The moduli SUX0(r;P0) of rank r vector bundles on X0 with determinant P0 is not compact. In [A], using the technique of Kausz ([K1], [K2]), we constructed a compactification GSL2B(X0;P0) of SUX0(2;P0), and studied its structure. Surprisingly, despite its seemingly natural definition,...
