NEW INTEGRABLE EXTENSIONS OF N=2 KdV AND BOUSSINESQ HIERARCHIES
نویسنده
چکیده
We construct a new variety of N = 2 supersymmetric integrable systems by junction of pseudo-differential superspace Lax operators for a = 4, N = 2 KdV and multi-component N = 2 NLS hierarchies. As an important particular case, we obtain Lax operator for N = 4 super KdV system. A similar extension of one of N = 2 super Boussinesq hierarchies is given. We also present a minimal N = 4 supersymmetric extension of the second flow of N = 4 KdV hierarchy and comment on its possible integrability.

A new Lax operator is proposed from the viewpoint of constructing the integrable hierarchies related with N = 2 super Wn algebra. It is shown that the Poisson algebra associated to the second Hamiltonian structure for the resulted hierarchy contains the N = 2 super Virasoro algebra as a proper subalgebra. The simplest cases are discussed in detail. In particular, it is proved that the supersymm...
متن کاملAlgebraic Properties of Gardner’s Deformations for Integrable Systems
An algebraic definition of Gardner’s deformations for completely integrable bi-Hamiltonian evolutionary systems is formulated. The proposed approach extends the class of deformable equations and yields new integrable evolutionary and hyperbolic Liouville-type systems. An exactly solvable two-component extension of the Liouville equation is found. Introduction. We consider the problem of constru...
متن کاملThe N = 2 super W 4 algebra and its associated generalized KdV hierarchies
We construct the N = 2 super W4 algebra as a certain reduction of the second Gel’fand-Dikii bracket on the dual of the Lie superalgebra of N = 1 super pseudodifferential operators. The algebra is put in manifestly N = 2 supersymmetric form in terms of three N = 2 superfields Φi(X), with Φ1 being the N = 2 energy momentum tensor and Φ2 and Φ3 being conformal spin 2 and 3 superfields respectively...
متن کاملSingular sector of the KP hierarchy, ∂̄-operators of non-zero index and associated integrable systems
Integrable hierarchies associated with the singular sector of the KP hierarchy, or equivalently, with ∂̄-operators of non-zero index are studied. They arise as the restriction of the standard KP hierarchy to submanifols of finite codimension in the space of independent variables. For higher ∂̄-index these hierarchies represent themselves families of multidimensional equations with multidimensiona...
متن کاملThe Moyal Momentum algebra applied to θ - deformed 2 d conformal models and KdV - hierarchies
The properties of the Das-Popowicz Moyal momentum algebra that we introduce in hep-th/0207242 are reexamined in details and used to discuss some aspects of integrable models and 2d conformal field theories. Among the results presented we setup some useful convention notations which lead to extract some non trivial properties of the Moyal momentum algebra. We use the particular sub-algebra sln−Σ̂...
