摘要:

The central results of this article are two theorems onGŌandGprimitivity on relative level 1 of the Kac module⫫(⋀) for the Lie superal-gebraG=sl(m/n). These theorems are combined with Kac module homomorphisms in order to prove a conjecture by Hughes et al. [HKV] on the number of composition factors of the Kac module for 3- andr- fold atypical highest weights ofsl(3/3) andsl(rZ/r) respectively. Our theorems onGŌandGprimitivity are general in nature and therefore the results also include infinite-dimensional representations.

摘要:

The nucleus of a Malcev superalgebraMmeasures how far it is from being a Lie superalgebraMbeing a Lie superalgebra if and only if its nucleus is the wholeM. This paper is devoted to study Malcev superalgebras in the opposite direction, that is, with trivial nucleus. The odd part of any finite-dimensional Malcev superalgebra with trivial nucleus is shown to be contained in the solvable radical. For algebraically closed fields, any such superalgebra splits as the sum of its solvable radical and a semisimple Malcev algebra contained in the even part, which is a direct sum of copies ofsl(2, F) and the seven-dimensional simple non-Lie Malcev algebra, obtained from the Cayley-Dickson algebra.
