There exists the Krichever map from the set of quintets (C,p,F,t,e) (where Cis an integral and complete algebraic curve, p a smooth rational point, F arank 2 torsion free coherent sheaf on C, t a local formal parameter in p and ea formal trivialization of F around p) to the ...

A coherent sheaf on Y is called torsion free if it does not have any non zero subsheaf with finite support. We prove that torsion free sheaves are reflexive. We study then the quasi locally free sheaves, i.e., sheaves which are locally isomorphic to direct sums of the OCi.We define ...

如果我们把 H^{2}(X;\underline{U(1)}) 的元素看成 X 上的U(1) gerbe(下划线表示sheaf of U(1)-valued functions), \hat{H}^{3}(X) 就是U(1)- gerbe with connection,那么 \hat{H}^{3}_{\Gamma}(X)的元素就是 \Gamma -equivariant U(1) gerbe。我们上述提到的lifting的非唯一性由kernel...
Kernel bundlesGlobal sections boundGlobally generatedWe show the kernel sheaf associated to a sufficiently positive torsion-free sheaf of rank one is slope stable. Furthermore, we are able to give an explicit bound for "sufficiently positive." This settles a conjecture of Ein–Lazarsfeld–Mustopa....
We show that under the Fourier-Mukai transform $\\Phi$ on $D^b(X)$ induced by the classical Fourier-Mukai transform on $D^b(C)$, a slope stable torsion-free sheaf satisfying a vanishing condition in codimension 2 (e.g. a reflexive sheaf) is taken to a limit tilt stable object. ...
