ELSV型公式中变量的变化

Changes of variables in ELSV-type formulas

Sergey Shadrin, Dimitri Zvonkine

摘要:

在[5] I.P. Goulden,D.M. Jackson和R.瓦基尔提出了一个猜想,将某些赫维茨数(列举球面上的分歧覆盖)与一个代数皮卡簇上的相交理论联系起来。我们将使用他们的公式来研究这个簇的相交理论(如果它曾经被构造的话),方法与M. Kazarian和S. Lando在[7]中。特别地,我们证明了一个Witten-Kontsevich型定理的相交理论和可积族。我们还推广了文[7]的结果,使之包括了模空间上的Hodge积分,其中涉及一个类.

英文摘要:

In [5] I.P. Goulden, D.M. Jackson, and R. Vakil formulated a conjecture relating certain Hurwitz numbers (enumerating ramified coverings of the sphere) to the intersection theory on a conjectural Picard variety. We are going to use their formula to study the intersection theory on this variety (if it is ever to be constructed) by methods close to those of M. Kazarian and S. Lando in [7]. In particular, we prove a Witten-Kontsevich-type theorem relating the intersection theory and integrable hierarchies. We also extend the results of [7] to include the Hodge integrals over the moduli spaces, involving one lambda-class.
