摘要：
In this paper, some special rings such as von Neumann regular rings and PP rings are characterized in terms of endomorphisms of divisible and torsionfree modules. In addition, commutative P-coherent rings and von Neumann regular rings are characterized by properties of homomorphism modules of certain special modules.
