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

Normally the subscript should mean something the constant evolved in \ll depend on, but this case it looks weird.

Rank one and nonzero ==> generic isomorphism, and torsionfree ==> injective (The kernel is supported on a proper closed subset, thus torsion.)
