Let K be a field, let A be an associative, commutative K-algebra, and let โฌ be a nonzero K-vector space of commuting K-derivations of A. Then, with a rather natural definition, A m โฌ s Aโฌ becomes a Lie algebra and we obtain necessary K and sufficient conditions here for this Lie algebra to be simple

โฆ Synopsis
The notion of a strongly nilpotent element of a Lie algebra is introduced. According to the existence or nonexistence of nontrivial strongly nilpotent elements, the simple modular Lie algebras are divided into two categories, CA type and CL type, which coincide with Lie algebras of generalized Cartan type and classical type, respectively, when the characteristic is greater than 7. Examples of nonclassical simple Lie algebras of CL type are given which all have affinities to the classical Lie algebras. ๏ฃฉ 2002 Elsevier Science (USA)

The cores of extended affine Lie algebras of reduced types were classified except for type A 1 . In this paper we determine the coordinate algebra of extended affine Lie algebras of type A 1 . It turns out that such an algebra is a unital n -graded Jordan algebra of a certain type, called a Jordan t
We classify all the pairs of a commutative associative algebra with an identity element and its finite-dimensional locally finite Abelian derivation subalgebra such that the commutative associative algebra is derivation-simple with respect to the derivation subalgebra over an algebraically closed fi
