Abstract We explain how to obtain new classical integrable field theories by assembling two affine Gaudin models into a single one. We show that the resulting affine Gaudin model depends on a parameter γ in such a way that the limit γ → 0 corresp

Abstract A three-parameter integrable deformation of ℤ 4 permutation supercosets is constructed. These supercosets are of the form F ^ / F 0 $$ \widehat{F}/{F}_0 $$ where F 0 is the bosonic diagonal subgroup of the product supergroup F ^ = G ^ × G

We consider σ-models on para-complex ZT-cosets, which are analogues of those on complex homogeneous target spaces considered recently by D. Bykov. For these models, we show the existence of a gauge-invariant Lax connection whose Poisson brackets are

We construct manifestly N=4 supersymmetric off-shell superfield actions for the HKT d=1 sigma models on the group manifolds U(2) and SU(3), using the harmonic d=1 approach. The underlying (4,4,0) and (4,4,0)⊕(4,4,0) multiplets are described, respec

Abstract A multi-parameter integrable deformation of the principal chiral model is presented. The Yang-Baxter and bi-Yang-Baxter σ-models, the principal chiral model plus a Wess-Zumino term and the TsT transformation of the principal chiral model ar

We define a two-parameter family of integrable deformations of the principal chiral model on an arbitrary compact group. The Yang–Baxter σ-model and the principal chiral model with a Wess–Zumino term both correspond to limits in which one of the

An integrable deformation of the type IIB AdS5×S5 superstring action is presented. The deformed field equations, Lax connection, and κ-symmetry transformations are given. The original psu(2,2|4) symmetry is expected to become q deformed.

We give a gauge invariant formulation of $N=2$ supersymmetric abelian Toda field equations in \n2 superspace. Superconformal invariance is studied. The conserved currents are shown to be associated with Drinfeld-Sokolov type gauges. The extension to

Generalized KdV hierarchies associated by Drinfeld-Sokolov reduction to grade one regular semisimple elements from non-equivalent Heisenberg subalgebras of a loop algebra $\G\otimes{\bf C}[\lambda,\lambda^{-1}]$ are studied. The graded Heisenberg sub
