Abstract:
In the nonisospectral case, we introduce the associated spectral problem with a perturbation term. We obtain a generalized nonisospectral super AKNS hierarchy and a coupled generalized nonisospectral super AKNS hierarchy associated with generalized Lie superalgebras $sl(2,1)$ and $sl(4,1)$. Based on a new type of multicomponent Lie superalgebra $sl(2N,1)$, a multicomponent generalized nonisospectral super AKNS hierarchy is obtained. By using the supertrace identity, the super bi-Hamiltonian structures of the resulting superintegrable hierarchies are obtained.
Keywords:Lie superalgebra, super Hamiltonian structure, multicomponent generalized super AKNS hierarchy.
