KP Integrability of Triple Hodge Integrals: III—Cut-and-Join Description, KdV Reduction, and Topological Recursions

A Alexandrov - Communications in Mathematical Physics, 2024 - Springer
In this paper, we continue our investigation of the triple Hodge integrals satisfying the Calabi–
Yau condition. For the tau-functions, which generate these integrals, we derive the complete …

KP integrability of triple Hodge integrals. II. Generalized Kontsevich matrix model

A Alexandrov - Analysis and Mathematical Physics, 2021 - Springer
In this paper we introduce a new family of the KP tau-functions. This family can be described
by a deformation of the generalized Kontsevich matrix model. We prove that the simplest …

KP hierarchy for Hurwitz-type cohomological field theories

R Kramer - arXiv preprint arXiv:2107.05510, 2021 - arxiv.org
We generalise a result of Kazarian regarding Kadomtsev-Petviashvili integrability for single
Hodge integrals to general cohomological field theories related to Hurwitz-type counting …

The ordered exponential representation of GKM using the W1+∞ operator

G Wang - Journal of High Energy Physics, 2023 - Springer
A bstract The generalized Kontsevich model (GKM) is a one-matrix model with arbitrary
potential. Its partition function belongs to the KP hierarchy. When the potential is monomial, it …

A natural basis for intersection numbers

B Eynard, D Lewański - arXiv preprint arXiv:2108.00226, 2021 - arxiv.org
We advertise elementary symmetric polynomials $ e_i $ as the natural basis for generating
series $ A_ {g, n} $ of intersection numbers of genus g and n marked points. Closed …

A connection between the Kontsevich-Witten and Brezin-Gross-Witten tau-functions

G Wang - arXiv preprint arXiv:1710.07764, 2017 - arxiv.org
The Brezin-Gross-Witten (BGW) model is one of the basic examples in the class of non-
eigenvalue unitary matrix models. The generalized BGW tau-function $\tau_N $ was …

[PDF][PDF] VIRASORO CONJECTURE FOR HODGE INTEGRALS AND DR FORMULA FOR CHERN CHARACTER OF HODGE BUNDLE

XIN WANG - researchgate.net
The purpose of this paper is to study the genus-g degree-g Ln-constraints in Virasoro
conjecture for Hodge integrals over smooth projective varieties. Results consist of the …

From Kontsevich-Witten to linear Hodge integrals via Virasoro operators

G Wang - Journal of Mathematical Physics, 2018 - pubs.aip.org
We give a proof of Alexandrov's conjecture on a formula connecting the Kontsevich-Witten
and Hodge tau-functions using only the Virasoro operators. This formula has been …
