| Research Abstract |
The study of von Neumann regular rings was first begun from the study of commutative von Neumann regular rings and the study of continuous von Neumann regular rings which contain self-injective von Neumann regular rings. Recently, the investigation of von Neumann regular rings with comparabilities has been proceeded by many ring theorists. Historically, the main themes for studies of von Neumann regular rings are the investigations of finiteness, characteristics and constructions. In this research, we investigated finiteness, hereditarity to matrix rings, cancellations and constructions on von Neumann regular rings with various comparabilities, to construct the theory of von Neumann regular rings with comparabilities.
