摘要
引入n-Ding投射模和n-Ding内射模,讨论了两类模的同调性质,研究了模的n-Ding投射性在优越扩张下的遗传性。
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.
