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
In a recent paper by Xu, some simple Lie algebras of generalized Cartan type were constructed, using the mixtures of grading operators and down-grading operators. Among them are the simple Lie algebras of generalized Witt type, which are in general nongraded and have no torus. In this paper, some representations of these simple Lie algebras of generalized Witt type are presented.

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
Let F be a field of characteristic p ) 0, L a generalized restricted Lie algebra ลฝ . over F, and P L the primitive p-envelope of L. A close relation between ลฝ .

We construct four new series of generalized simple Lie algebras of Cartan type, using the mixtures of grading operators and down-grading operators. Our results in this paper are further generalizations of those in Osborn's work (J. Algebra 185 (1996), 820-835).
