| Outline of Final Research Achievements |
It is expected to develop geometry on discrete objects in connections not only to mathematics but also to other fields in natural sciences. Our research focuses on problems in mathematics and related fields, in particular analysis on discrete groups and graphs, as they form an active research area in recent years. The topic is also related to mathematical aspects of computer sciences and statistical physics. In order to deepen our understanding on discrete groups, we introduced a new class of groups, and have studied its basic property.
This clarified its relations to other well-studied groups which had been difficult to analyze.
