We identify the moduli space \(\cdot \mathscr{h}_{n, d}\) of semistable bundles of rank \(n\) and degree \(d\) on an elliptic curve \(C\) as a symmetric product of the curve, its dimension being the greatest common divisor of \(n\) and \(d\). Under this identification the determinant map det: \(\mat

โฆ Synopsis
In this Note we study indecomposable vector bundles of degree zero over an elliptic curve. We show that each bundle generates a ring and a Tannakian category, such that the ring and the group scheme associated to the Tannakian category are of the same dimension. Furthermore we show that the result does not extend to curves of genus 2.

Here we study vector bundles on elliptic curves over a DVR. In particular, we classify the vector bundles whose restriction to the special fiber is stable. For singular genus one curves over a DVR, we consider the same problem for flat sheaves whose restriction to the special fiber is torsion free a
## Abstract We review the notions of symplectic and orthogonal vector bundles over curves, and the connection between principal parts and extensions of vector bundles. We give a criterion for a certain extension of rank 2__n__ to be symplectic or orthogonal. We then describe almost all of its rank
