Abstract
In [1] the notion of n-coherent modules are introduced and studied. In this paper, we introduce and study a dual notion of n-coherent modules which we call it n-co-coherent modules.
Keywords: Finitely copresented modules, finitely generated modules, finitely presented modules, a finitely cogenerated module, a coherent module, a co-coherent module, a coherent ring and a co-coherent ring, n-coherent modules, n-co-coherent modules, n-coherent rings and n-co-coherent rings
