Faltings' annihilator theorem
In abstract algebra (specifically commutative ring theory), Faltings' annihilator theorem states: given a finitely generated module M over a Noetherian commutative ring A and ideals I, J, the following are equivalent:
- for any ,
- there is an ideal in A such that and annihilates the local cohomologies ,
provided either A has a dualizing complex or is a quotient of a regular ring.
The theorem was first proved by Faltings in (Faltings 1981).
