Since quasicoherence is a local condition, the criterion would presumably use local cohomology or something like that. The "surjectivity" condition seems to be an "almost flasque"-ness condition, and the "injectivity" condition seems to be a "controlled torsion" condition.... both of which sound "cohomological" in nature... | |
