关于对角调和的商环

On the quotient ring by diagonal harmonics

Iain Gordon

摘要:

对于外尔群W及其反射表示mathfrak{h},通过一个包含无常数项的W-不变多项式的理想,求出C[mathfrak{h} o + mathfrak{h}^*]的商环的特征标和Hilbert级数.这证实了海曼的证词。证明利用合理的切雷德尼克代数,研究了埃廷夫和金兹伯格,和其他人。

英文摘要:

For a Weyl group W and its reflection representation mathfrak{h}, we find the character and Hilbert series for a quotient ring of C[mathfrak{h} oplus mathfrak{h}^*] by an ideal containing the W--invariant polynomials without constant term. This confirms conjectures of Haiman. The proof makes use of rational Cherednik algebras, as studied by Etingof and Ginzburg, and others.
