We examine the question of the integrability of the recently defined Z2 × Z2-graded sine-Gordon model, which is a natural generalisation of the supersymmetric sine-Gordon equation. We do this via appropriate auto-Bäcklund transformations, construction of conserved spinor-valued currents and a pair of infinite sets of conservation laws.

Double-Graded Supersymmetric Quantum Mechanics
A quantum mechanical model that realizes the $ \mathbb{Z}_2 \times \mathbb{Z}_2$-graded generalization of the one-dimensional supertranslation algebra is proposed. This model shares some featuresExpand
$\cal N$-Extension of duble-graded supersymmetric and superconformal quantum mechanics.
In the recent paper, Bruce and Duplij introduced a double-graded version of supersymmetric quantum mechanics (SQM). It is an extension of Lie superalgebraic nature of ${\cal N}=1$ SQM to aExpand
An Infinite Set of Conservation Laws of the Supersymmetric {Sine-Gordon} Theory
Abstract We find an ansatz for the explicit expression for an infinite set of bosonic conserved currents of the supersymmetric sine-Gordon theory. The corresponding charges all commute with theExpand
On integrability aspects of the supersymmetric sine-Gordon equation
In this paper we study certain integrability properties of the supersymmetric sine-Gordon equation. We construct Lax pairs with their zero-curvature representations which are equivalent to theExpand
On a Z n 2-Graded Version of Supersymmetry
We extend the notion of super-Minkowski space-time to include Zn 2 -graded (Majorana) spinor coordinates. Our choice of the grading leads to spinor coordinates that are nilpotent but commute amongstExpand
N=2 Superconformal Affine Liouville Theory
We present a new supersymmetric integrable model: the N = 2 superconformal affine Liouville theory. It interpolates between the N = 2 super Liouville and N = 2 super sine-Gordon theories andExpand
Z2×Z2-graded mechanics: The quantization
Abstract In a previous paper we introduced the notion of Z 2 × Z 2 -graded classical mechanics and presented a general framework to construct, in the Lagrangian setting, the worldline sigma modelsExpand
Integrable N=2 supersymmetric field theories
Abstract A classification is given of Toda-like theories with N = 2 supersymmetry which are integrable by virtue of some underlying Lie superalgebra. In addition to the N = 2 superconformal theoriesExpand
Pfaffian solutions for the Manin-Radul-Mathieu SUSY KdV and SUSY sine-Gordon equations
We reduce the vectorial binary Darboux transformation for the Manin-Radul supersymmetric KdV system in such a way that it preserves the Manin-Radul-Mathieu supersymmetric KdV equation reduction.Expand
The category of Z n 2-supermanifolds
In Physics and in Mathematics Zn 2 -gradings, n ≥ 2, appear in various fields. The corresponding sign rule is determined by the ‘scalar product’ of the involved Zn 2 -degrees. The Z n 2Expand
