Hello, I am sorry if this question is not appropriate for MO. Suppose $X$ is the affine line, $i:Z\to X$ is the origin, and $j: U \to X$ is the complement to $Z$ in $X$. I then have a distinguished ...
Let $X$ be a smooth variety, $\mathcal D$ the sheaf of algebraic differentail operators, $\Omega$ the algebraic deRham complex and $\mathcal M$ a quasi coherent $\mathcal O_X$-module. Now there is a ...
Is there any work describing (indecomposable)projectives, injectives in category of D-modules on some flag variety? I wonder whether someone has used quivers(say Auslander-Reiten sequences)to ...
For geometric representation theorists down here. Consider the Beilinson-Bernstein theorem: Functor of global sections establishes the correspondence between twisted D-modules with fixed ...
