该文利用形式分布李代数的相关结论,详细刻划并分类了一类与Schrdinger Virasoro李代数相关的秩为3的李共形代数的结构.所考虑到的Schrdinger Virasoro李共形代数是一类以{L_n,I_n,Y_n|n∈Z}为基的李代数,其中基元素之间的关系式是[L_m,L_n]=(m-n)L_(m+n),[L_m,I_n]=-nI_(m+n),[L_m,Y_n]=(m/2-n)Y_(m+n),[Y_m,I_n]=[I_m,I_n]=0,[Y_m,Y_n]=(m-n)I_(m+n). 相似文献

For each simply-laced Dynkin graph Δ we realize the simple complex Lie algebra of type Δ as a quotient algebra of the complex
degenerate composition Lie algebra of a domestic canonical algebra A of type Δ by some ideal I of that is defined via the Hall algebra of A, and give an explicit form of I. Moreover, we show that each root space of has a basis given by the coset of an indecomposable A-module M with root easily computed by the dimension vector of M.

In this paper we generalize naturally graded filiform Lie algebras as well as filiform Lie algebras admitting a connected gradation of maximal length, by introducing the concept of c-graded complex filiform Lie algebras. We deal with the particular case of 3-graded filiform Lie algebras and we obtain their classification in arbitrary dimension. We finally show a link among derived algebras, graded filiform and rigid solvable Lie algebras. 相似文献

A Lie isomorphism ? between algebras is called trivial if ?=ψ+τ, where ψ is an (algebraic) isomorphism or a negative of an (algebraic) anti-isomorphism, and τ is a linear map with image in the center vanishing on each commutator. In this paper, we investigate the conditions for the triviality of Lie isomorphisms from reflexive algebras with completely distributive and commutative lattices (CDCSL). In particular, we prove that a Lie isomorphism between irreducible CDCSL algebras is trivial if and only if it preserves I-idempotent operators (the sum of an idempotent and a scalar multiple of the identity) in both directions. We also prove the triviality of each Lie isomorphism from a CDCSL algebra onto a CSL algebra which has a comparable invariant projection with rank and corank not one. Some examples of Lie isomorphisms are presented to show the sharpness of the conditions. 相似文献

Let г denote a connected valued Auslander-Reiten quiver, let ℒ(γ) denote the free abelian group generated by the vertex setγ
0 and let ℒ(Γ) be the universal cover ofг with fundamental groupG. It is proved that whenγ is a finite connected valued Auslander-Reiten quiver,ℒ(γ) is a Lie subalgebra ofℋ(г), and is just the “orbit” Lie algebra ℒ(
)/G, where ℋ (г)1 is the degenerate Hall algebra ofг and ℒ(
)/G is the “orbit” Lie algebra induced by

In this paper, we introduce the notion of a Minkowski Lie algebra, which is the natural generalization of the notion of a
real quadratic Lie algebra (metric Lie algebra). We then study the positive definite Minkowski Lie algebras and obtain a complete
classification of the simple ones. Finally, we present some applications of our results to Finsler geometry and give a classification
of bi-invariant Finsler metrics on Lie groups.

We study the exponential growth of the codimensions of a finite dimensional Lie algebra over a field of characteristic zero. In the case when is semisimple we show that exists and, when is algebraically closed, is equal to the dimension of the largest simple summand of . As a result we characterize central-simplicity: is central simple if and only if .
