Abstract: n-Ding projective and n-Ding injective modules are introduced, the homological properties of these two kinds of modules are discussed, and the hereditary property of the n-Ding projectiveness of module under the excellent extension is investigated.

Key words: n-Ding projective module, n-Ding injective module, n-Ding projective dimension, n-Ding injective dimension
