| In the thesis,we introduce the concepts of FP_n-exact sequence and FP_n-projective and FP_n-injective modules based on a finitely n-presented module,and give a definition of FP_n-exact complex.We show that the homological properties of FP_n-exact complexes,and construct FP_n-injective resolutions of left bounded complexes of modules.Furthermore,we investigate the existences of the FP_n-injective resolutions of unbounded complexes. |
