We develop a theory of general sheaves over weighted projective lines. We define and study a canonical decomposition, analogous to Kac’s canonical decomposition for representations of quivers, study subsheaves of a general sheaf, general ranks of morphisms, and prove analogues of Schofield’s results on general representations of quivers. Using these, we… (More)
