从Hurwitz数到Kontsevich-Witten τ-函数:Virasoro算子的联系

From Hurwitz numbers to Kontsevich-Witten tau-function: a connection by Virasoro operators

A. Alexandrov

摘要:

在这封信中,我们提出了我们的猜想之间的连接Kontsevich-Witten和Hurwitz tau-功能。结构式通过$GL(\infty)$群元素连接这两个τ函数。这个群元素的一个重要特征是它的简单性:这是$gl(\infty)$的Virasoro子代数的群元素。如果被证明,这个猜想将允许导出的维拉索罗约束的赫维茨τ函数,这仍然是未知的,尽管存在几个矩阵模型表示,以及给出一个可积的运营商描述的Kontsevich-Witten τ函数。

英文摘要:

In this letter,we present our conjecture on the connection between the Kontsevich--Witten and the Hurwitz tau-functions. The conjectural formula connects these two tau-functions by means of the $GL(\infty)$ group element. An important feature of this group element is its simplicity: this is a group element of the Virasoro subalgebra of $gl(\infty)$. If proved, this conjecture would allow to derive the Virasoro constraints for the Hurwitz tau-function, which remain unknown in spite of existence of several matrix model representations, as well as to give an integrable operator description of the Kontsevich--Witten tau-function.
