摘要：

Using Nisnevich coverings and a Hilbert stack of stacky points, we prove etale devissage results for non-representable etale and quasi-finite flat coverings. We give applications to absolute noetherian approximation of algebraic stacks and compact generation of derived categories. (C) 2017 Elsevier Inc. All rights reserved.
