Outline of Final Research Achievements

In Noncommutative Algebraic Geometry, at first,
Artin-Schelter tried to classify all 3-dimensional AS-regular algebras and gave a partial list of regular potential. Also, Mori-Smith proved that there is one-to-one correspondence between a 3-dimensional AS-regular algebra and regular twisted superpotential. In this research joint work with Masaki Matsuno, we gave the lists of regular twisted superpotential and Calabi-Yau superpotential for any 3-dimensional Koszul AS-regular algebra except for elliptic curves.

Academic Significance and Societal Importance of the Research Achievements

本研究結果の応用として,任意の3次元コシュールAS正則環に対して, ある3次元コシュール Calabi-Yau AS 正則環が存在し,これらは次数付き森田同値であることを示した。これは全ての射影平面は座標環としてCalabi-Yau AS 正則環を持つことを示唆する。この結果はコシュール双対を介することで多元環の表現論の考察対称となるが,任意の根基の4乗が0となるフロべニウス多元環に対して,ある対称なコシュール多元環が存在し,これらは次数付き森田同値であることを得た。これは次数がついていない多元環では起こらないため,次数付き多元環と次数付きでない多元環との差を示す更なる結果を与えたと言えよう。
