WebDerived completion for comodules 413 5.37], and the definition of Z in terms of I, we see that the corresponding subcate-gories of complete objects, resp. torsion objects, are equivalent as well. On the other hand, the category of quasi-coherent sheaves over X is a Grothendieck abelian category, and so we can consider its derived category

WebDERIVED COMPLETION FOR COMODULES TOBIAS BARTHEL, DREW HEARD, AND GABRIEL VALENZUELA Abstract. The objective of this paper is to introduce and study completions and local ho- mology of comodules over Hopf algebroids, extending previous work of Greenlees and May in the discrete case. WebMay 1, 2024 · Since perfectoid ring theory makes heavy use of derived completion and adic flatness, we anticipate that our results shall help simplify and improve some of the more technical aspects of this theory. WebNov 16, 2012 · Let A be a commutative ring, and ${\\mathfrak{a}}$ a weakly proregular ideal in A. This includes the noetherian case: if A is noetherian then any ideal in it is weakly proregular; but there are other interesting examples. In this paper we prove the MGM equivalence, which is an equivalence between the category of cohomologically … software to open gif file
