| Outline of Final Research Achievements |
We call that R is a Harada ring if any non-small R-module contains a non-zero injective submodule. This ring is carried out intensive research by the researchers of Artinian ring, including the principal investigator of this study. The results are gotten together, and it has been published by World Scientific Publ. as a book co-authored with the principal investigator of this study and Kiyoichi Oshiro, Professor Emeritus of Yamaguchi University. However, what is written there is the research results of one-sided Harada ring, it remains untouched with respect to two-sided Harada rings.
In this study, we worked on the structure of two-sided Harada rings. In particular, focusing on the position of i-pair, by examining the relation of right Harada rings and left Harada rings, we studed the structure of two-sided Harada rings.
