摘要
给出了p-torsion模的定义,并利用同调的方法讨论了p-torsion模的性质,目的是找到p-torsion模构成torsion类的条件以及构造p-torsionfree类,并最终找到了一个p-torsionfree类与投射维类的关系。
The definition of the p-torsion module is given and the properties of P-torsion modules are discussed by homological method. The purpose of this paper is finding the condition in which P-torsion modules form a torsion class and how to form the corresponding torsionfree class. At last, the relation between P-torsionfree class and projective dimensions is obtained.
