| 研究実績の概要 |
There are many interesting opportunities presented within the host institution, and I have explored some new collaborations in research within Japan. In particular, I start to look at the structure of differential graded modules as a category. Our current goal is to transfer the machinery of perverse equivalence to the differential graded setting and apply to silting theory. Besides, I have also initiated a project to study Frobenius extriangulated category with Laurent Demonet, in hope to enrich the theory which unify techniques on exact categories and those on triangulated category, both of which are crucial in various aspect of representation theory. Also, I am in the process of writing up two other independent results on group algebras of special linear group of degree 2.

2: おおむね順調に進展している
理由
We have studied some properties of derived category of differential graded modules and identify some questions that need to be addressed to achieve the aim of the project.
|
| 今後の研究の推進方策 |
To understand deeper connections between perverse equivalences and silting theory, we will try to establish a parallel notion of Serre subcategory in differential graded setting, or to see why this is not possible. To achieve this a better understanding of category of differential graded modules is needed.
