是一个素特征的代数闭域且~$\frak{gl}(2,\mathbb{F})$
是系数在~$\mathbb{F}$ 上的~$2\times 2$ 阶矩阵李代数.
计算出所有~$\frak{gl}(2,\mathbb{F})$

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. 相似文献

In this paper F always denotes a field of characteristic P>2.We construct the finitedimensional modular Lie superalgebra W(m,n,l,(t))over a field F,define θ-type derivation and determine the derivation superalgebra of w(m,n,l,(t)). 相似文献

Motivated by Schur-concavity, we introduce the notion of G -concavity where G is a closed subgroup of the orthogonal group O ( V ) on a finite dimensional real inner product space V . The triple ( V , G , F ) is an Eaton triple if F ² V is a nonempty closed convex cone such that (A1) Gx 7 F is nonempty for each x ε V . (A2) max g ε G ( x,gy ) = ( x,gy ) for all x, y ε F . If W := span F and H := { g | W : g ε G , gW = W } ² O ( W ), and ( W , H , F ) is an Eaton triple, then ( W , H , F ) is called a reduced triple of the Eaton triple ( V , G , F ). In this event, a characterization of the G -concavity in terms of H -concavity is obtained. Some differential characterizations of G -concavity are then given. The results are applied to Lie groups. Various matrix examples are given. 相似文献

In this note is given an example of a 2-component ribbon link with trivial components, which has the same Alexander module as a trivial 2-component link and (hence) whose longitudes lie in the second commutator subgroup of the link group, yet which is not even an homology boundary link. This answers two questions raised by R.H. Fox and N.F. Smythe at the 1965 Wisconsin Topology Conference. 相似文献

In this paper, all Lie bialgebra structures on the Lie algebras of generalized Witt type are considered. It is proved that, for any Lie algebra W of generalized Witt type, all Lie bialgebras on W are the coboundary triangular Lie bialgebras. As a by-product, it is also proved that the first cohomology group H1(W, W(?)W) is trivial. 相似文献

In this paper, it is proved that a monomial derivation d of k[x, y, z] has no Darboux polynomials if and only if d is a strict derivation with a trivial ring of constants, and we give the specific conditions when it has no Darboux polynomials. 相似文献

In this paper, we compute the idempotents of the ring $$F_+(G)$$ as defined by Boltje (J Algebra 206:293–343, 1998) in the particular case when the Green biset functor F is such that for all subgroups H of a finite group G, F(H) is a torsion-free ring, finitely-generated as an Abelian group, and has only the trivial idempotents. In this case, the only idempotents in $$F_+(G)$$ are those arising from the Burnside ring B(G). 相似文献
