Lemma 85.36.6. Let $S$ be a scheme. Let $X$ be an algebraic space over $S$. Let $U$ be a simplicial algebraic space over $S$. Let $a : U \to X$ be an augmentation. Let $\mathcal{F}$ be an abelian sheaf on $X_{\acute{e}tale}$. Let $\mathcal{F}_ n$ be the pullback to $U_{n, {\acute{e}tale}}$. If $U$ is a ph hypercovering of $X$, then there exists a canonical spectral sequence
\[ E_1^{p, q} = H^ q_{\acute{e}tale}(U_ p, \mathcal{F}_ p) \]
converging to $H^{p + q}_{\acute{e}tale}(X, \mathcal{F})$.
