Abstract
Giving a cotorsion pair in an abelian category \({\mathscr {C}}\), we have a sequence of exact functors between triangulated categories with respect to the pair, and construct right (left) adjoints of the exact functors such that the sequence is a (co)localization sequence. Further, for some especial cotorsion pairs, we gain a recollement and triangle-equivalences between corresponding triangulated categories. In particular, let (\({\mathcal {A}}, {\mathcal {Z}}, {\mathcal {B}}\)) and (\({\mathcal {A}}_{1}, {\mathcal {Z}}_{1}, {\mathcal {B}}_{1}\)) be two complete and hereditary cotorsion triples in \({\mathscr {C}}\) with \({\mathcal {A}}_{1}\subseteq {\mathcal {A}}\). We obtain a triangle-equivalence \(K({\mathcal {A}})\simeq K({\mathcal {B}})\), which restricts to an equivalence \(K({\mathcal {A}}_{1})\simeq K({\mathcal {B}}_{1})\).
