摘要

我们研究与超几何型卡多姆采夫-彼得维亚什维利(KP)陶函数(又称奥尔洛夫-舍尔宾分割函数)相对应的 n $n$ 点微分,重点是它们的 ℏ 2 $\hbar ^2$ 变形和展开。在自然所需的分析假设下,我们证明了某些更高的循环方程,其中尤其包含标准的线性和二次循环方程,从而暗示了绽放拓扑递归。我们还区分了两个确实满足自然解析假设的奥尔洛夫-舍宾分割函数大家族,对于这些大家族,我们还证明了所谓的投影性质,从而证明了契科夫-艾纳德-奥兰汀拓扑递归的完整陈述。我们论证的一个特别之处在于,它完全澄清了分割函数的奥尔洛夫-舍宾参数的ℏ 2 $\hbar ^2$变形的作用,我们从早先在此方向上获得的各种结果中知道了其必要性,但从未在拓扑递归的背景下正确理解过。作为本文结果的特例,我们对以前研究过的所有与加权双赫尔维茨数有关的枚举问题的拓扑递归进行了新的统一证明。凭借拓扑递归和格罗thendieck-Riemann-Roch 公式,这反过来又给出了文献中讨论的几乎所有 Ekedahl-Lando-Shapiro-Vainshtein (ELSV) 类型公式的新的统一证明。

Topological recursion for Kadomtsev–Petviashvili tau functions of hypergeometric type

We study the n $n$ -point differentials corresponding to Kadomtsev–Petviashvili (KP) tau functions of hypergeometric type (also known as Orlov–Scherbin partition functions), with an emphasis on their 2 $\hbar ^2$ -deformations and expansions. Under the naturally required analytic assumptions, we prove certain higher loop equations that, in particular, contain the standard linear and quadratic loop equations, and thus imply the blobbed topological recursion. We also distinguish two large families of the Orlov–Scherbin partition functions that do satisfy the natural analytic assumptions, and for these families, we prove in addition the so-called projection property and thus the full statement of the Chekhov–Eynard–Orantin topological recursion. A particular feature of our argument is that it clarifies completely the role of 2 $\hbar ^2$ -deformations of the Orlov–Scherbin parameters for the partition functions, whose necessity was known from a variety of earlier obtained results in this direction but never properly understood in the context of topological recursion. As special cases of the results of this paper, one recovers new and uniform proofs of the topological recursion to all previously studied cases of enumerative problems related to weighted double Hurwitz numbers. By virtue of topological recursion and the Grothendieck–Riemann–Roch formula, this, in turn, gives new and uniform proofs of almost all Ekedahl–Lando–Shapiro–Vainshtein (ELSV)-type formulas discussed in the literature.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
