Vector bundles over curves of genus one and arbitrary index, by S. Pumplün
Vector bundles on curves of genus one and arbitrary index are investigated
and classified, extending Atiayh's results on curves of genus one over
algebraically closed fields. For instance, absolutely indecomposable bundles
have certain admissible slopes which depend on the index of the curve.
