Representation theoretical research on algebraic structures of rings and module categories

我们研究了有限维代数的结构和代数上的模的范畴，取得了许多成果，包括开放问题的解。这些结果在国内或国际会议和专题讨论会上公布，并在英文期刊上发表。通过在东京组织一次代数表示的国际会议，我们对表示理论的发展做出了巨大的贡献。会议记录和一本基于我们研究的书的第一卷由欧洲数学学会出版。

We studied structures of finite dimensional algebras and categories of modules over the algebras, so that we have achieved many results including solutions of open problems. Those results were announced at domestic or international conferences and symposiums and were published in refereed journals in English. By organizing an international conference on representations of algebras in Tokyo, we made an enormous contribution to the development of the representation theory. The proceedings of the conference and the first volume of a book based on our research were published from the European Mathematical Society.
