| Feb 8, 2010 at 12:27 | comment | added | Clark Barwick | You probably know about this, but David Rydh wrote a beautiful paper, Noetherian approximation of algebraic spaces and stacks. In Rydh's case, he's approximating an algebraic stack $X$ with a system $\{X_{\lambda}\}$ of others, and studying the circumstances under which one may translate useful properties between $X$ and a cofinal subsystem of the $X_{\lambda}$. But I think you're asking something slightly different: if we have a fixed system of stacks approximating an algebraic one, can we conclude that a cofinal system of those is algebraic? | |
