Cartan型广义李超代数

设F是特征不为2的域.本文定义了F上的广义李超代数，证明了Z-阶化广义李超代数的单性准则.然后定义了有限维Cartan型广义李超代数W(n),证明了W(n)的单性.最后指出对Cartan型广义李超代数S(n)与H(n)，亦有与W(n)相似的结果.     

非单W和S型李超代数的滤过和分类

设F是特征p3的域,g是F上外代数与有限维广义Witt李代数或特殊李代数的张量积所构成的有限维非单李超代数.本文通过确定ad幂零元的方法证明了g的标准滤过是g的自同构群的不变量,进而证明了定义这类李超代数的参数组是内蕴的,从而给出了这两类李超代数在同构意义下的分类.     

一类广义W型李超代数

构造了一类有限维广义Caxtan型模李超代数W,并证明了它是李超代数W(n)的一个扩张,进而决定了它的导子超代数.     

一类广义W型李超代数

构造了一类有限维广义Cartan型模李超代数W,并证明了它是李超代数W(n)的一个扩张,进而决定了它的导子超代数.     

有限维模李超代数(-W)

本文构造了有限维模李超代数(-W).利用已有的模李超代数W(m,n,t_),证明了(-W)是单李超代数,获得了(-W)是限制李超代数的一个充分必要条件,进而证明了-W没有非退化结合型.     

无限维L-型模李超代数

研究素特征域上无限维L-型李超代数.证明了它的单性,利用ad-幂零元,证明了L-型李超代数的自然滤过在其自同构下是不变的.由此可得到L-型李超代数的一个特性.     

系数在结合超代数的矩阵李超代数的2-上循环

设α是域F上的结合超代数满足[α,α]=a或a=F.证明了当m+n＞1时,H2(glm|n(α),F)≌HC1(a,F).定义了一大类广义微分算子李超代数,作为W-无穷代数W∞(glN)的推广.确定了这些李超代数的2-上循环.同时给出了矩阵量子微分算子李超代数的2-上同调群.     

素特征域上广义Witt李超代数的自同构群

设W是素特征域上无限维或有限维广义Witt李超代数.本文利用W的自然滤过不变性和W的底代数的不变维数性质,证明了W的自同构群AutW同构于W的底代数的容许自同构群,还证明了在此群同构之下,AutW的标准正规列恰好对应W的底代数的容许自同构群的标准正规列,并给出AutW若干较为细致的性质.     

Witt型李超代数的极大根阶化子代数

设W(m,n)是特征p3的代数闭域上有限维Witt型李超代数.证明了W(m,n)的极大根阶化子代数一定是其极大Z-阶化子代数,从而刻画了W(m,n)的所有极大根阶化子代数.结果有助于理解Witt型李超代数W(m,n)的内在性质.     

李超代数不可分解表示的Boson—Fermion实现

本文从普遍的代数观点出发,考虑到李超代数的Boson-Fermion实现,研究了任意李超代数在Heisenberg-Weyl超代数的通用包络代数相关空间上的无穷维不可分解表示。在特定的商空间上,这个表示将诱导出各种有限维表示,通常的不可约表示仅作为特殊情况给出。作为具体例子,我们给出了典型李超代数Gsl(2)(B(0,1),在耦合基下的不可分解表示。最后,我们证明了荷载这种无穷维不可分解表示的商空间同构于物理空间——广义Fock空间。     

Super-biderivations of not-finitely graded Lie superalgebras related to generalized super-Virasoro algebras

We mainly study the super-biderivations of not-finitely graded Lie superalgebras related to generalized super-Virasoro algebras. In particular, we prove that all super-biderivations of not-finitely graded Lie superalgebras related to generalized super-Virasoro algebras are inner.     

Quadratic Lie Superalgebras Generalized by Balinsky–Novikov Superalgebras

Balinsky–Novikov superalgebras were introduced by Balinsky for constructing super-Virasoro type Lie superalgebras. In this paper, we give sufficient and necessary conditions for a Lie superalgebra generalized by a Balinsky–Novikov superalgebra with dimension 2|2 to be a quadratic Lie superalgebra.     

Some properties of generalized reduced Verma modules over ℤ-graded modular Lie superalgebras

We study some properties of generalized reduced Verma modules over ?-graded modular Lie superalgebras. Some properties of the generalized reduced Verma modules and coinduced modules are obtained. Moreover, invariant forms on the generalized reduced Verma modules are considered. In particular, for ?-graded modular Lie superalgebras of Cartan type we prove that generalized reduced Verma modules are isomorphic to mixed products of modules.     

关于单李超三系的分类(英文)

本文证明了特征零代数闭域上的单李超三系可分为两部分:一是将单李超代数视为李超三系;二是单李超代数的对合自同构的(-1)-特征子空间.这些推广了Lister和Meyberg给出的关于单李三系分类的相应结果.     

Generalized P(N)-graded Lie superalgebras

We generalize the P(N)-graded Lie superalgebras of Martinez-Zelmanov. This generalization is not so restrictive but suffcient enough so that we are able to have a classification for this generalized P(N)-graded Lie superalgebras. Our result is that the generalized P(N)-graded Lie super-algebra L is centrally isogenous to a matrix Lie superalgebra coordinated by an associative superalgebra with a super-involution. Moreover, L is P(N)-graded if and only if the coordinate algebra R is commutative and the super-involution is trivial. This recovers Martinez-Zelmanov's theorem for type P(N). We also obtain a generalization of Kac's coordinatization via Tits-Kantor-Koecher construction. Actually, the motivation of this generalization comes from the Fermionic-Bosonic module construction.     

ON THE PRIMARY DECOMPOSITION THEOREM OF MODULAR LIE SUPERALGEBRAS

This gives some identities of associative Lie superalgebras and some properties of modular Lie superalgebras. Furthermore, the primary decomposition theorem of modular Lie superalgebras is shown. It is well known that the primary decomposition theorem of modular Lie algebras has played an important role in the classification of the finite-dimensional simple modular Lie algebras (see [5, 6]). Analogously, the primary decomposition theorem of modular Lie superalgebras may play an important role in the open classification of the finite dimensional simple modular Lie superalgebras.     

限制李超代数的环面秩

本文将模李代数中环面与环面秩的理论推广到模李超代数中.应用模李超代数的限制包络得到了环面秩的若干重要性质.作为应用,计算了典型李超代数slm|n与限制Cartan型李超代数W(m,n,1),S(m,n,1)的绝对环面秩及S(m,n,1)在W(m,n,1)中的环面秩.     

Extended affine Lie superalgebras and their affinizations

Extended affine Lie superalgebras are super versions of the defining axioms of extended affine Lie algebras or more generally invariant affine reflection algebras. This class includes finite dimensional basic classical simple Lie superalgebras and affine Lie superalgebras. In this paper, an affinization process is introduced for the class of extended affine Lie superalgebras, and the necessary conditions for an extended affine Lie superalgebra to be invariant under this process are presented. Moreover, new extended affine Lie superalgebras are constructed by means of the affinization process.
