Generalized quasi-coherent sheafcotorsion representationtorsion free coverThe category of quasi-coherent sheaves on the projective lineP1(k) (k is a field) is equivalent tocertain representations of the quiver u2022 u2192 u2022 u2190 u2022.Many of the techniques which are used to study these ...
The quot functor of a quasi-coherent sheaf We build an infinite dimensional scheme parametrizing isomorphism classes of coherent quotients of a quasi-coherent sheaf on a projective scheme. The main tool to achieve the construction is a version of Grothendieck's Grassmannian embed... GD Brino 被引...

Note that OX itself is not a quasi-coherent module, but rather a sheaf of generalized rings. Every morphism of generalized schemes f:Y→X induces a cocontinuous tensor functor ⁎f⁎:Qcoh(X)→Qcoh(Y), and our aim will be to show that as before, this implements an equivalence of ...
We define the rank of a quasicoherent sheaf on T that can take arbitrary nonnegative real values. We study the category Qcoh( 畏 T ) obtained by taking the quotient of the category of quasicoherent sheaves by the subcategory of objects of rank zero (called torsion sheaves ). We show ...
It is proved in this note that on a locally noetherian scheme X the two "local cohomologies" with respect to an arbitrary closed subset Y coincide for any quasicoherent sheaf of modules on X."doi:10.1016/0021-8693(88)90103-2A Verschoren...
We give a definition of quasi-coherent modules for any presheaf of sets on the categories of affine commutative and non-commutative schemes. This definition generalizes the usual one. We study the property of a quasi-coherent module to be a sheaf in various topologies. Using presheaves of group...

If X is coherent and n-perfect(not necessarily of finite krull dimension), we prove that every at quasi-coherent sheaf has finite pure injective dimension. Also, we show that there is an equivalence K(PinfX)---> D(FlatX) of homotopy categories, whenever K(PinfX) is the homotopy ...
