Abstract
Let be a locally Noetherian scheme with a closed subscheme . Let be the completion of at , considered as a formal scheme. We show that a coherent sheaf on is equivalently given by a coherent sheaf on , a coherent sheaf on the complement of , and an isomorphism of pullbacks of these sheaves to a certain adic space . By defining as an adic space instead of as a Berkovich space we are able to generalize the descent result of Ben-Bassat and Temkin from finite type -schemes to locally Noetherian schemes.
