a minor typo

Commentary on algebraic stacks from categories.

Added clarification on non-invertible morphisms

| Mar 1, 2011 at 14:10 | comment | added | shenghao | Dear Torsten: Could you explain a little more about the last paragraph? I thought when doing descent, one still needs "transition isomorphisms" rather than non-isomorphisms, so I got confused by what you mean. Thanks! | |
