| 研究実績の概要 |
Over the past year I have a new publication and have two other papers submitted for review.
One of the two submitted paper is directly related to the current KAKENHI project. Namely, we achieved a major step in our research plan, which is to classify torsion classes of gentle algebras using surface combinatorics. The other two paper are related to cluster-tilting theory. The published paper studies the classification of representation-finite gendo-symmetric algebras, which contains some of the Brauer graph algebras - one of the subject of interest in our KAKENHI project. The other project shows that fractional-Calabi-Yau property of an algebra reflects periodicity of its trivial extension. This has potential applications to many algebras appear in, for example, algebraic geometry.

| 今後の研究の推進方策 |
I am now attempting to relate gentle algebras with non-orientable surfaces, on top of the known orientable case. And aim to use this to give a categorification of the coordinate ring of decorated Techmuller space of non-orientable surfaces, just like the classical case does.
