Lemma 59.51.10. Let I be a directed set. Let g_ i : X_ i \to S_ i be an inverse system of morphisms of schemes over I. Assume g_ i is quasi-compact and quasi-separated and for i' \geq i the transition morphisms X_{i'} \to X_ i and S_{i'} \to S_ i are affine. Let g : X \to S be the limit of the morphisms g_ i, see Limits, Section 32.2. Denote f_ i : X \to X_ i and h_ i : S \to S_ i the projections. Let \mathcal{F} be an abelian sheaf on X. Then we have

R^ pg_*\mathcal{F} = \mathop{\mathrm{colim}}\nolimits _{i \in I} h_ i^{-1}R^ pg_{i, *}(f_{i, *}\mathcal{F})

Proof. Formal combination of Lemmas 59.51.8 and 59.51.9. \square
