Kadomtsev–Petviashvili Hierarchy: Negative Times

open access: yesMathematics, 2021
The Kadomtsev–Petviashvili equation is known to be the leading term of a semi-infinite hierarchy of integrable equations with evolutions given by times with positive numbers. Here, we introduce new hierarchy directed to negative numbers of times.

Lax pairs for new ZN-symmetric coset σ-models and their Yang-Baxter deformations

open access: yesNuclear Physics B, 2022
Two-dimensional σ-models with ZN-symmetric homogeneous target spaces have been shown to be classically integrable when introducing WZ-terms in a particular way. This article continues the search for new models of this type now allowing some kinetic terms

Deformation conjecture: deforming lower dimensional integrable systems to higher dimensional ones by using conservation laws

open access: yesJournal of High Energy Physics, 2023
Utilizing some conservation laws of (1+1)-dimensional integrable local evolution systems, it is conjectured that higher dimensional integrable equations may be regularly constructed by a deformation algorithm.

Constraint and Nonlinearization of Supersymmetric Equations with Some Special Forms of Lax Pairs

open access: yesAdvances in Mathematical Physics, 2020
We study the null boundary problems of some classical evolution equations constrained by some special forms of Lax pairs. Furthermore, we present the constraint and nonlinearization of some supersymmetric (SUSY) equations with a special form of Lax pairs

R-matrix-valued Lax pairs and long-range spin chains

open access: yesPhysics Letters B, 2018
In this paper we discuss R-matrix-valued Lax pairs for slN Calogero–Moser model and their relation to integrable quantum long-range spin chains of the Haldane–Shastry–Inozemtsev type.

O(d,d) transformations preserve classical integrability

open access: yesNuclear Physics B, 2020
In this note, we study the action of O(d,d) transformations on the integrable structure of two-dimensional non-linear sigma models via the doubled formalism.

Symmetry Reductions of (2 + 1)-Dimensional CDGKS Equation and Its Reduced Lax Pairs

open access: yesJournal of Applied Mathematics, 2014
With the aid of symbolic computation, we obtain the symmetry transformations of the (2 + 1)-dimensional Caudrey-Dodd-Gibbon-Kotera-Sawada (CDGKS) equation by Lou’s direct method which is based on Lax pairs. Moreover, we use the classical Lie group method

Self-adaptive moving mesh schemes for short pulse type equations and their Lax pairs [PDF]

open access: yes, 2014
Integrable self-adaptive moving mesh schemes for short pulse type equations (the short pulse equation, the coupled short pulse equation, and the complex short pulse equation) are investigated.

Lax pairs for integrable lattice systems [PDF]

open access: yesJournal of Mathematical Physics, 1999
This paper studies the structure of Lax pairs associated with integrable lattice systems (where space is a one-dimensional lattice, and time is continuous). It describes a procedure for generating examples of such systems, and emphasizes the features that are needed to obtain equations which are local on the spatial lattice.
