    局所関数等式が正則概均質ベクトル空間の基本相対不変式とその双対空間の多項式のペアから与えられることは知られている。我々は Clifford quartic form と呼ばれるある4次斉次多項式を構成し, それが概均質ベクトル空間の相対不変式ではないにも関わらず局所関数等式を満たすことを示した。局所関数等式を満たす多項式を特徴付ける問題は興味深い未解決問題であるが, この問題に関連し、 Etingof, Kazhdan, Polishchuk は(もっと一般的な設定で)ある予想を提示した。我々は、 Clifford quartic form を用いて, この予想に反例があることを示した。 (この講演は佐藤文広氏との共同研究に基づいている。)

    今まで、関数等式を満たす多項式は概均質ベクトル空間の相対不変式くらいしか知られていなかったが、それくらいしかないのかどうかを探る研究で、Clifford代数の表現などから、そのような多項式が構成でき、それらは概均質ベクトル空間の理論ではカヴァーされないことを証明する。その例をもとに表現論的、解析的研究を行う。
