WebThe subsheaf is a coherent sheaf on Yi which has rank one and depth one. Fur- thermore, the section si is nonzero generically on Yi , because there is no unrelated polygon for W with more than m vertices by Theorem 3.6. Let (s1 , . . . , sm ) denote the corresponding section of the sum Mm M := Ker(ψi ). ... WebAny finite type subsheaf of a coherent sheaf is coherent. Let be a morphism from a finite type sheaf to a coherent sheaf . Then is of finite type. Let be a morphism of coherent -modules. Then and are coherent. Given a short exact sequence of -modules if two out of three are coherent so is the third. The category is a weak Serre subcategory of .

The set of points where the coherent subsheaf F is not locally free is a proper closed subset of … On an arbitrary ringed space quasi-coherent sheaves do not necessarily form an abelian category. On the other hand, the quasi-coherent sheaves on any scheme form an abelian category, and they are extremely useful in that context. On any ringed space , the coherent sheaves form an abelian category, a full subcategory of the category of -modules.
