Abstract
The moduli space M0 of semi-stable rank 2 vector bundles with fixed trivial determinant over a non-hyperelliptic curve C of genus 3 is isomorphic to a quartic hypersurface in P 7 (Coble’s quartic). We show that M0 is self-dual and that its polar map associates to a stable bundle E ∈ M0 a bundle F which is characterized by dim H 0 (C, E ⊗ F) = 4. The projective

Moduli of Abelian Varieties, Vinberg θ-Groups, and Free Resolutions

TL;DR: In this article, a systematic approach to studying the geometric aspects of Vinberg θ-representations is presented, using the Borel-Weil construction for representations of reductive groups as sections of homogeneous bundles on homogeneous spaces, and then to study degeneracy loci of these vector bundles.

Vector bundles and theta functions on curves of genus 2 and 3

TL;DR: In this paper, it was shown that the SIcir moduli space of vector bundles of rank r and trivial determinant on a smooth projective complex curve is a normal projective variety, which can be considered as a nonabelian analogue of the Jacobian variety JC.

Vector bundles on curves and theta functions

TL;DR: In this paper, a survey lecture on the "theta map" from the moduli space of SL_r bundles on a curve C to the projective space of r-th order theta functions on JC is presented.

Projective duality and a Chern-Mather involution

TL;DR: In this paper, the authors deduce the existence of an explicit involution on a part of the Chow group of projective space, encoding the effect of duality on Chern-Mather classes.
