A multi-component super integrable Dirac hierarchy

open access: yesPhysics Letters B, 2023
We propose a method for generating higher-dimensional nonisospectral super integrable coupling hierarchies associated with a new type of higher-dimensional Lie superalgebra.

Generating of Nonisospectral Integrable Hierarchies via the Lie-Algebraic Recursion Scheme

open access: yesMathematics, 2020
In the paper, we introduce an efficient method for generating non-isospectral integrable hierarchies, which can be used to derive a great many non-isospectral integrable hierarchies.

Duality of Positive and Negative Integrable Hierarchies via Relativistically Invariant Fields

open access: yesJournal of High Energy Physics, 2021
It is shown that the relativistic invariance plays a key role in the study of integrable systems. Using the relativistically invariant sine-Gordon equation, the Tzitzeica equation, the Toda fields and the second heavenly equation as dual relations, some ...

Self-Consistent Sources and Conservation Laws for Nonlinear Integrable Couplings of the Li Soliton Hierarchy

open access: yesAbstract and Applied Analysis, 2013
New explicit Lie algebras are introduced for which the nonlinear integrable couplings of the Li soliton hierarchy are obtained. Then, the nonlinear integrable couplings of Li soliton hierarchy with self-consistent sources are established.

Symmetries and integrable systems [PDF]

open access: yesFundamental Research
Symmetry plays key roles in modern physics especially in the study of integrable systems because of the existence of infinitely many local and nonlocal generalized symmetries.

A Few Integrable Couplings of Some Integrable Systems and (2+1)-Dimensional Integrable Hierarchies [PDF]

open access: yesAbstract and Applied Analysis, 2014
Two high-dimensional Lie algebras are presented for which four (1+1)-dimensional expanding integrable couplings of the D-AKNS hierarchy are obtained by using the Tu scheme; one of them is a united integrable coupling model of the D-AKNS hierarchy and the

Overview of the Kadomtsev–Petviashvili-hierarchy reduction method for solitons

open access: yesPartial Differential Equations in Applied Mathematics, 2022
The Kadomtsev–Petviashvili (KP) hierarchy reduction method is a prominent direct method for deriving explicit solutions to integrable equations. This method is based on Hirota’s bilinear formulation of integrable systems, as well as the observation that ...

Hamiltonian structures for integrable hierarchies of Lagrangian PDEs [PDF]

open access: yesOpen Communications in Nonlinear Mathematical Physics, 2021
Many integrable hierarchies of differential equations allow a variational description, called a Lagrangian multiform or a pluri-Lagrangian structure. The fundamental object in this theory is not a Lagrange function but a differential $d$-form that is ...

A generalized isospectral–nonisospectral heat equation hierarchy and its expanding integrable model

open access: yesAdvances in Difference Equations, 2020
A generalized nonisospectral heat integrable hierarchy with three dependent variables is singled out. A Bäcklund transformation of a resulting isospectral integrable hierarchy is produced by converting the usual Lax pair into the Lax pairs in Riccati ...

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.
