Given two complete hereditary cotorsion pairs (Q, R) and (Q′, R′) in a bicomplete abelian category G such that Q′⊆ Q and Q∩ R= Q′∩ R′, Becker showed that there exists a hereditary abelian model structure M=(Q, W, R′) on G, where W is a thick subcategory of G. We prove that the homotopy category Ho (M) of M is triangulated equivalent to the triangulated quotient category D b (G)[Q, R′] ˆ/K b (Q′∩ R′), where D b (G)[Q, R′] ˆ is the subcategory of D b (G) consisting of all homology bounded complexes with both finite Q dimension and R′ dimension and K b (Q′∩ R′) is the bounded homotopy category of Q′∩ R′(core) objects. Applications are given in the category of modules. It is shown that the homotopy category of the Gorenstein flat (resp., Ding projective and Gorenstein AC-projective) model structure on the category of modules established by Gillespie and his coauthors can be realized as a certain triangulated quotient category.
