本文给出了Z-阶化有限维单李超代数具有非退化亦型的一个必要条件。应用这一结果,我们可以得到Cartan型李超代数X(n)与X(m,n,t)的Killing型是退化的。 相似文献

Superderivations for the eight families of finite or infinite dimensional graded Lie superalgebras of Cartan-type over a field of characteristic p?>?3 are completely determined by a uniform approach: The infinite dimensional case is reduced to the finite dimensional case and the latter is further reduced to the restrictedness case, which proves to be far more manageable. In particular, the structures and dimension formulas are clearly described for the outer superderivation algebras of those Lie superalgebras. Certain known results are also covered. 相似文献

By means of generators, superderivations are completely determined for a family of Lie superalgebras of special type, the tensor products of the exterior algebras and the finite-dimensional special Lie algebras over a field of characteristic p〉3. In particular, the structure of the outer superderivation algebra is concretely formulated and the dimension of the first cohomology group is given. 相似文献

ABSTRACT Let A = A 0 ⊕ A 1 be an associative superalgebra over a commutative associative ring F, and let Z s (A) be its supercenter. An F-mapping f of A into itself is called supercentralizing on a subset S of A if [x, f(x)] s ∈ Z s (A) for all x ∈ S. In this article, we prove a version of Posner's theorem for supercentralizing superderivations on prime superalgebras. 相似文献

It is well-known how the representation theory of the Lie algebra sl(2, ?) can be used to prove that certain sequences of integers are unimodal and that certain posets have the Sperner property. Here an analogous theory is developed for the Lie superalgebra osp(1,2). We obtain new classes of unimodal sequences (described in terms of cycle index polynomials) and a new class of posets (the “super analogue” of the lattice L(m,n) of Young diagrams contained in an m × n rectangle) which have the Sperner property. 相似文献
