Dijkgraaf-Vafa β-系综中可积性的评论

Comment on integrability in Dijkgraaf-Vafa beta-ensembles

A. Mironov, A. Morozov, Z. Zakirova

摘要:

我们简要地讨论了最近的索赔,普通KP/Toda可积性,这是一个普通的特征值矩阵模型的特性,也持续的Dijkgraaf-Vafa(DV)配分函数和细化拓扑顶点。我们强调,在这两种情况下,所指的是配分函数的一种特殊表示:在第一种情况下,所有DV相位的一个特殊和,在第二种情况下,将变形参数隐藏在一个复杂的势中,即本质上是用旧理论的语言重新表述新理论中的一些问题。如果这种处理能够与AGT关系一致,甚至与Nekrasov-Shatashvili极限中的基本可积系统的量子化一致,这似乎需要对单个DV配分函数进行全尺度β变形,那么这充其量是模糊的。因此,目前还不清楚可积性的故事是否真的被这些最近的考虑所终结。

英文摘要:

We briefly discuss the recent claims that the ordinary KP/Toda integrability, which is a characteristic property of ordinary eigenvalue matrix models, persists also for the Dijkgraaf-Vafa (DV) partition functions and for the refined topological vertex. We emphasize that in both cases what is meant is a particular representation of partition functions: a peculiar sum over all DV phases in the first case and hiding the deformation parameters in a sophisticated potential in the second case, i.e. essentially a reformulation of some questions in the new theory in the language of the old one. It is at best obscure if this treatment can be made consistent with the AGT relations and even with the quantization of the underlying integrable systems in the Nekrasov-Shatashvili limit, which seem to require a full-scale beta-deformation of individual DV partition functions. Thus, it is unclear if the story of integrability is indeed closed by these recent considerations.
