Abstract:
We show that an iteration of the procedure used to define Ding projective modules yields exactly Ding projective modules. Then we introduce Ding projective complexes,and characterize those complexes by Ding projective modules. Moreover,we characterize n-FC rings with Ding projective dimension of complexes. Finally,we prove that the category of Ding projective complexes also has some kind of stability.
