关于量子KdV族的谱问题

On the spectral problem of the quantum KdV hierarchy

Giulio Ruzza, Di Yang

摘要:

量子色散的Korteweg-de Vries(KdV)族的谱问题,又称量子Hopf族,由Dubrovin解决。本文在Dubrovin的基础上,研究了Buryak-Rossi的量子KdV族。特别地,我们证明了量子KdV哈密顿量的对称性和非简并性。在此基础上,我们构造了一个完整的公共特征向量集。这个频谱问题的分析意味着某些消失的身份组合的字符的对称群。我们还评论的量子KdV层次的光谱曲线的几何形状,我们给出了一个表示的量子色散KdV哈密顿算子的乘法算子的类代数的对称群。

英文摘要:

The spectral problem for the quantum dispersionless Korteweg-de Vries (KdV) hierarchy, aka the quantum Hopf hierarchy, is solved by Dubrovin. In this article, following Dubrovin, we study Buryak-Rossi's quantum KdV hierarchy. In particular, we prove a symmetry property and a non-degeneracy property for the quantum KdV Hamiltonians. On the basis of this we construct a complete set of common eigenvectors. The analysis underlying this spectral problem implies certain vanishing identities for combinations of characters of the symmetric group. We also comment on the geometry of the spectral curves of the quantum KdV hierarchy and we give a representation of the quantum dispersionless KdV Hamiltonians in terms of multiplication operators in the class algebra of the symmetric group.
