We investigate purities determined by classes of finitely presented modules including the
correspondence between purities for left and right modules. We show some cases where …

Let R be a ring, X a class of R-modules and n≥ 1 an integer. We introduce the concepts of
Gorenstein nX-injective and nX-flat modules via special finitely presented modules. Besides …

Several authors have introduced various types of coherent-like rings and proved analogous
results on these rings. It appears that all these relative coherent rings and all the used …

n-coherent rings in terms of complexes Page 1 Hacettepe Journal of Mathematics and
Statistics Volume 44 (3) (2015), 521 – 533 n-coherent rings in terms of complexes Lu Bo ∗ and …

Coherent rings were first introduced by Chase as a generalization of right Noetherian rings.
His characterization has led to several generalizations of this concept. n-coherent rings have …
