Definition 103.17.2. Let \mathcal{X} be a locally Noetherian algebraic stack. An \mathcal{O}_\mathcal {X}-module \mathcal{F} is called coherent if \mathcal{F} satisfies one (and hence all) of the equivalent conditions of Lemma 103.17.1. The category of coherent \mathcal{O}_\mathcal {X}-modules is denote \textit{Coh}(\mathcal{O}_\mathcal {X}).
