COMPLETION BY DERIVED DOUBLE CENTRALIZER
COMPLETION BY DERIVED DOUBLE CENTRALIZER

arXiv:1207.0612v2 [math.AC] 21 Jan 2013 COMPLETION BY DERIVED ,DOUBLE CENTRALIZER, MARCO PORTA, LIRAN SHAUL AND AMNON YEKUTIELI Abstract. Let A be a commutative ring, and let a be a weakly proregular ideal in A. (If A is noetherian then any ideal in it is weakly proregular.) Suppose M is a compact generator of the category of cohomologically a-torsion complexes
