On Covers of Perfect Lie Algebras

Algebra Colloquium, 2011
A Lie algebra is said to be perfect when it coincides with its derived subalgebra. The paper is devoted to give a complete structure of covers of perfect Lie algebras. Also, similar to a result of Alperin and Gorenstein (1966) in group theory, it is shown that every automorphism of a finite dimensional perfect Lie algebra may be lifted to an ...

Algebraic Modelling of Covering Arrays

2017
We introduce a novel technique to model and compute binary covering arrays, discrete combinatorial structures, based on a tuple-level modelling and using methods arising from linear algebra, commutative algebra and symbolic computation. Concrete instances of covering arrays for given parameters will arise as points in a generated variety of a system of

Covering points in permutation algebras

Archiv der Mathematik, 2013
In this note we extend the main result of [8] concerning covering blocks of group algebras to the context of p-permutation algebras over arbitrary ground fields. We also establish several connections between the Green correspondence for points and the correspondences that arise using the Brauer homomorphism.
