Lemma 58.24.2. Let (A, \mathfrak m) be a Noetherian local ring. Let f \in \mathfrak m. Assume
A is f-adically complete,
f is a nonzerodivisor,
H^1_\mathfrak m(A/fA) and H^2_\mathfrak m(A/fA) are finite A-modules,
for every maximal ideal \mathfrak p \subset A_ f purity holds for (A_ f)_\mathfrak p.
Then the restriction functor \textit{FÉt}_ U \to \textit{FÉt}_{U_0} is essentially surjective.
