Outline of Annual Research Achievements

当該年度は以下の研究を行った。
W代数の幾何学的実現のためにaffine Slodowy vareity を導入し、その研究を行った。(Anne Moreau, 桑原俊郎との共同研究)。未知の部分も多くまた技術的に難しい所を含む問題を含み、,最終結果にはもう少し時間を要するように感じるが様々な応用が考えられ、今度の進展が期待される。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

おおむね正しい方向に進んでいると思われる。

Strategy for Future Research Activity

affine Slodowy vareityやaffine Springer fiberを軸としてW代数の幾何学的実現を実行する。未知の部分も多く技術的に難しい所を含むため、多くの研究者と議論を交わし知見を深める予定である。

Causes of Carryover

研究者の招聘が次年度に延期になったため。

Expenditure Plan for Carryover Budget

招聘旅費に使用する。
