- Abstract
In this paper, we construct some model structures corresponding Gorenstein (ℒ ,) -modules and relative Gorenstein flat modules associated to duality pairs, Frobenius pairs and cotorsion pairs. By investigating homological properties of Gorenstein (ℒ ,) -modules and some known complete hereditary cotorsion pairs, we describe several types of complexes and obtain some characterizations of Iwanaga–Gorenstein rings. Based on some facts given in this paper, we find new duality pairs and show that ℐ is covering as well as enveloping and ℱ is preenveloping under certain conditions, where ℐ denotes the class of Gorenstein (ℒ ,) -injective modules and ℱ denotes the class of Gorenstein (ℒ ,) -flat modules. We give some recollements via projective cotorsion pair ( , ⊥) cogenerated by a set, where denotes the class of Gorenstein (ℒ ,) -projective modules. Also, many recollements are immediately displayed through setting specific complete duality pairs. [ABSTRACT FROM AUTHOR]
