Affine Lie Algebra Modules and Complete Lie Algebras
Algebra Colloquium, 2006In this paper, we first construct some new infinite dimensional Lie algebras by using the integrable modules of affine Lie algebras. Then we prove that these new Lie algebras are complete. We also prove that the generalized Borel subalgebras and the generalized parabolic subalgebras of these Lie algebras are complete.

Russian Mathematical Surveys, 1976
In this article we investigate the structure of local Lie algebras with a one-dimensional fibre. We show that all such Lie algebras are essentially exhausted by the classical examples of the Hamiltonian and contact Poisson bracket algebras. We give some examples, unsolved problems, and applications of Lie superalgebras.

Algebra, Lie Group and Lie Algebra
2010Geometry, algebra, and analysis are usually called the three main branches of mathematics. This chapter introduces some fundamental results in algebra that are mostly useful in systems and control. In section 4.1 some basic concepts of group and three homomorphism theorems are discussed. Ring and algebra are introduced briefly in section 4.2. As a tool,

In this paper we attempt to define the notion of normed Lie algebra by endowing the corresponding algebraic concept with topologicalmetric properties. More precisely, we define normed Lie algebras as being normed spaces possessing a Lie product, the latter satisfying a ...

The Quarterly Journal of Mathematics, 1993
The author provides detailed information for the nilpotency class of Lie algebras (over a field \(k\)) satisfying the Engel condition \((\operatorname {ad}b)^n= 0\) for all \(b\), \(n=3,4\). The author shows that for \(n=3\), \(\operatorname {char}k\neq 2,5\), the nilpotency class is \(\leq 4\) (which is the best possible result) and for \(n=4 ...

Our aim in this paper is to study a certain class of Lie algebras which arose naturally in (4). In (4), we showed that beginning with an indecomposable symmetrizable generalized Cartan matrix (A ij) and a field Φ of characteristic zero, we could construct a Lie algebra E((A ij)) over Φ patterned on the finite-dimensional split simple Lie algebras.

Mathematics of the USSR-Sbornik, 1986
In this paper general problems of the deformations of Lie algebras over a field of characteristic zero and related problems of calculating the cohomologies with coefficients in the adjoint representation are considered. The author adapts and generalizes to the case of Lie algebras the general constructions of the cohomology theory of (local ...

The author investigates Lie algebras which contain elements the squares of whose adjoint endomorphisms are zero. The basic theory is used, in particular, to improve the proof of the local nilpotence of Engel Lie algebras. Bibliography: 3 titles.
