For the orthosymplectic Lie superalgebra , we choose a set of basis matrices. A linear combination of those basis matrices presents a spatial spectral matrix. The compatible condition of the spatial part and the corresponding temporal parts of the spectral problem leads to a generalized super AKNS (GSAKNS) hierarchy. By making use of the supertrace identity, the obtained GSAKNS hierarchy can be written as the super bi-Hamiltonian structures. 相似文献

A new eight-dimensional Lie superalgebra and two corresponding hierarchies of evolution equations 下载免费PDF全文
A new eight-dimensional Lie superalgebra is constructed
and two isospectral problems with six potentials are designed.
Corresponding hierarchies of nonlinear evolution equations, as well
as super-AKNS and super-Levi, are derived. Their super-Hamiltonian
structures are established by making use of the supertrace identity,
and they are integrable in the sense of Liouville. 相似文献

In this paper, we introduce the supertrace identity and its applications. A new eight-dimensional Lie superalgebra is constructed and the super-Dirac hierarchy is derived. By the supertrace identity, we obtain the super-bi-Hamiltonian structure of the super-Dirac hierarchy. 相似文献

Based on the matrix Lie super algebra and supertrace identity, the integrable super-Geng hierarchy with self-consistent is established. Furthermore, we establish the in-finitely many conservation laws for the integrable super-Geng hierarchy. The methods de-rived by us can be generalized to other nonlinear equation hierarchies. 相似文献

Using the Moyal *-product and orthosymplectic supersymmetry, we construct a natural nontrivial supertrace and an associated
nondegenerate invariant supersymmetric bilinear form for the Lie superalgebra structure of the Weyl algebra W. We decompose
adjoint and twisted adjoint actions. We define a renormalized supertrace and a formal inverse Weyl transform in a deformation
quantization framework and develop some examples

It is shown that A:= H1, η (G), the sympectic reflection algebra over ?, has TG independent traces, where TG is the number of conjugacy classes of elements without eigenvalue 1 belonging to the finite group G ? Sp(2N) ? End(?2N) generated by the system of symplectic reflections.Simultaneously, we show that the algebra A, considered as a superalgebra with a natural parity, has SG independent supertraces, where SG is the number of conjugacy classes of elements without eigenvalue -1 belonging to G.We consider also A as a Lie algebra AL and as a Lie superalgebra AS.It is shown that if A is a simple associative algebra, then the supercommutant [AS, AS] is a simple Lie superalgebra having at least SG independent supersymmetric invariant non-degenerate bilinear forms, and the quotient [AL, AL]/([AL, AL] ∩ ?) is a simple Lie algebra having at least TG independent symmetric invariant non-degenerate bilinear forms. 相似文献
