In mathematics, the annihilator of a subset S of a module over a ring is the ideal formed by the elements of the ring that give always zero when multiplied by an element of S. Over an integral domain, a module that has a nonzero annihilator is a torsion module, and a finitely generated torsion module has a nonzero annihilator. The above definition applies also in the case noncommutative rings, where the left annihilator of a left module is a left ideal, and the right-annihilator, of a right module is a right ideal.

  • En théorie des anneaux, l'annulateur d'une partie S d'un module à gauche M sur un anneau A est l'ensemble : . Ann(S) est un idéal à gauche de A.
