An almost derived analogue of Nakayama's Lemma
AN ALMOST DERIVED ANALOGUE OF NAKAYAMA’S LEMMA
Abstract
Abstract. As Nakayama’s lemma, in commutative ring theory, it is well-known that the residue functor of
an ideal contained in the Jacobson radical is conservative. In almost mathematics setting, considering an
almost version of perfect complexes, we prove an almost derived analogue of Nakayama’s lemma, stating
the conservativity of the derived functor of the residue of a tight ideal contained in the Jacobson radical.
