双分歧型可积系统

Integrable systems of double ramification type

Alexandr Buryak, Boris Dubrovin, Jérémy Guéré, Paolo Rossi

摘要:

在本文中,我们研究的各个方面的双重分歧(DR)的层次,介绍了第一作者,其量化。我们将τ-对称性的概念推广到量子可积族,并证明了量子DR族具有这种性质。我们明确地确定了亏格$1$的量子修正,并作为应用,完全计算了$3$ -和$4$ -KdV体系(威滕的$3$ -和$4$ -自旋理论的DR体系)的量子化。然后,我们专注于DR哈密顿密度满足的递归关系,从它的几何起源抽象,我们用它来描述和构建一个新的家庭的量子和经典的可积系统,我们称之为双分歧型,因为它们满足DR层次的所有主要属性。在第二部分中,我们通过对构成双分歧τ-函数的算子的几何解释,对DR和Dubrovin-Zhang族之间的Miura等价猜想有了新的认识。然后,我们证明了DR和DZ层次之间的候选三浦变换(我们在以前的论文中唯一确定的)确实将Dubrovin-Zhang Poisson结构转化为标准形式。最后,我们专注于与秩- $1$上同调场论及其变形相关的可积族,并在此背景下证明了DR/DZ等价猜想到亏格$5$。

英文摘要:

In this paper we study various aspects of the double ramification (DR) hierarchy, introduced by the first author, and its quantization. We extend the notion of tau-symmetry to quantum integrable hierarchies and prove that the quantum DR hierarchy enjoys this property. We determine explicitly the genus $1$ quantum correction and, as an application, compute completely the quantization of the $3$- and $4$-KdV hierarchies (the DR hierarchies for Witten's $3$- and $4$-spin theories). We then focus on the recursion relation satisfied by the DR Hamiltonian densities and, abstracting from its geometric origin, we use it to characterize and construct a new family of quantum and classical integrable systems which we call of double ramification type, as they satisfy all of the main properties of the DR hierarchy. In the second part, we obtain new insight towards the Miura equivalence conjecture between the DR and Dubrovin-Zhang hierarchies, via a geometric interpretation of the correlators forming the double ramification tau-function. We then show that the candidate Miura transformation between the DR and DZ hierarchies (which we uniquely identified in our previous paper) indeed turns the Dubrovin-Zhang Poisson structure into the standard form. Eventually, we focus on integrable hierarchies associated with rank-$1$ cohomological field theories and their deformations, and we prove the DR/DZ equivalence conjecture up to genus $5$ in this context.
