| Outline of Final Research Achievements |
Sagbi basis is an analogue of Groebner basis for ideals, which is very widely investigated by many researchers in these days.
In this research, we investigated the action of groups to high dimensional array of datum, which is called a tensor and is widely investigated by many researchers in relation to data analysis, and the ring of invariants with respect to this group action. And we have succeeded in some cases of 3-dimensional tensors, finding the sagbi basis of the ring of invariants and therefore the ring of invariants under the action of special linear groups.
