Research Abstract

今年度は主に以下の結果を得た: (1)長方形のヤング図形に対応したA型の冪零元付随するにW代数の具体形を導出することに成功した(A. Molev氏 との共同研究)。(2) sl2のアフィンリー環に付随するパラフェルミオン代数とBRSTコホモロジーを用いて定義されるW代数が同型であることを示した(C.-H. Lam氏と山田裕理氏との共同研究)。(3) W代数の理論の応用として、centralizerに関するVinbergの問題を解く事に成功した(A. Premet氏との共同研究)。
またこれらの結果について国内外の研究集会などで講演を行った。

Current Status of Research Progress
Current Status of Research Progress

3: Progress in research has been slightly delayed.

Reason

他に優先すべき研究課題が見つかったため

Strategy for Future Research Activity

当該年度は当初の予定にない研究も行ったが、W代数とその応用という意味では研究テーマに合ったものであった。
これにより得たより知見を基に本来の予定の研究も行っていく。

Expenditure Plans for the Next FY Research Funding

当該年度は比較的長期(3ヶ月)の海外出張があったため
主に招へい旅費として使用する
