Extension groups of tautological bundles on symmetric products of curves

We provide a spectral sequence computing the extension groups of tautological bundles on symmetric products of curves. One main consequence is that, if E ≠ O X is simple, then the natural map Ext 1 ( E , E ) → Ext 1 ( E [ n ] , E [ n ] ) is injective for every n . Along with previous results, this i...
