An explicit construction of indecomposable vector bundles over an elliptic curve
In the celebrated paper “Vector bundles over an elliptic curve,” M. Atiyah classifies indecomposable vector bundles, namely he provides a bijection 
between indecomposable bundles of arbitrary rank 
and degree 
(denoted by 
) and 
(where 
). The latter is described explicitly: there is a distinguished element 
such that for any other …
