= Matlis duality
{wiki=Matlis_duality}
Matlis duality is a concept in commutative algebra that pertains to the study of modules over a Noetherian local ring. It provides a way to relate a module to a dual module that can reflect certain properties of the original module. Specifically, Matlis duality provides an equivalence between the category of finitely generated modules over a Noetherian local ring and the category of certain finitely generated modules over its completion.
