I'm working with Martin Olsson.
I'm interested in questions on Algebraic Geometry and stacks, but I also ask random questions. :)

What exactly does \gg and \ll mean?
Normally the subscript should mean something the constant evolved in \ll depend on, but this case it looks weird.

Families of ideal sheaves: What's the correct definition?
Rank one and nonzero ==> generic isomorphism, and torsionfree ==> injective (The kernel is supported on a proper closed subset, thus torsion.)

Characterization of schemes whose dualizing complex is perfect
Sure. I edited. What I wanted to ask is whether that $\omega_X$ being a perfect complex only happens in the Gorenstein case.
