چکیده
Suppose that the underlying field is of characteristic different from 2 and 3. We first prove so-called stem deformations a free presentation finite-dimensional Lie superalgebra L exhaust all maximal extensions L, up to equivalence extensions. Then we multipliers covers always exist for they are unique isomorphisms. Finally, describe multipliers, covers, Heisenberg superalgebras model filiform superalgebras.

Module Extensions over Classical Lie Superalgebras
We study certain filtrations of indecomposable injective modules over classical Lie superalgebras, applying a general approach for noetherian rings developed by Brown, Jategaonkar, Lenagan, and Warfield. To indicate the consequences of our analysis, suppose that g is a complex classical simple Lie superalgebra and that E is an indecomposable injective g-module with nonzero (and so necessarily s...
متن کاملCentral extensions of Steinberg Lie superalgebras of small rank
It was shown by A.V.Mikhalev and I.A.Pinchuk in [MP] that the second homology group H2(st(m,n,R)) of the Steinberg Lie superalgebra st(m,n,R) is trivial for m+n ≥ 5. In this paper, we will work out H2(st(m,n,R)) explicitly for m + n = 3, 4. Introduction Steinberg Lie algebras stn(R) play an important role in (additive) algebraic K-theory. They have been studied by many people (see [L] and [GS],...
متن کاملHom-Lie Superalgebras and Hom-Lie admissible Superalgebras
The purpose of this paper is to study Hom-Lie superalgebras, that is a superspace with a bracket for which the superJacobi identity is twisted by a homomorphism. This class is a particular case of Γ-graded quasi-Lie algebras introduced by Larsson and Silvestrov. In this paper, we characterize Hom-Lie admissible superalgebras and provide a construction theorem from which we derive a one paramete...
متن کاملGraded Lie Superalgebras, Supertrace Formula, and Orbit Lie Superalgebras
Let Γ be a countable abelian semigroup and A be a countable abelian group satisfying a certain finiteness condition. Suppose that a group G acts on a (Γ × A)-graded Lie superalgebra L = ⊕ (α,a)∈Γ×A L(α,a) by Lie superalgebra automorphisms preserving the (Γ × A)-gradation. In this paper, we show that the Euler-Poincaré principle yields the generalized denominator identity for L and derive a clos...
متن کاملStem Extensions and Stem Covers of Leibniz Algebras
Some properties on stem extensions and stem covers of Leibniz algebras are studied by means of exact sequences associated to a central extension of Leibniz algebras. We obtain particular results in case of perfect Leibniz algebras. 2000 Mathematics Subject Classification: 17A32.
