0.1. Let g be a complex finite-dimensional contragredient Lie superalgebra. These algebras were classified by V. Kac in [K1] and the list (excluding Lie algebras) consists of four series: A(m|n), B(m|n), C(m), D(m|n) and the exceptional algebrasD(2, 1, a), F (4), G(3). The finite-dimensional contragredient Lie superalgebras with zero Killing form (or, equivalently, with dual Coxeter number equa...

We describe transposed Poisson algebra structures on Block Lie algebras B(q) and superalgebras S(q), where q is an arbitrary complex number. Specifically, we show that the are trivial whenever q∉Z, for each q∈Z there only one (up to isomorphism) non-trivial structure B(q). The superalgebra S(q) admits q≠0 two non-isomorphic q=0. As a consequence, new admit Hom-Lie found.

In the present paper, we study notion of Schur multiplier M(L) an n-Lie superalgebra L=L0?L1 and prove that dim M(L)??i=0n(mi)L(n?i,k), where L0=m, L1=k, L(0,k)=1 L(t,k)=?j=1t(t?1j?1)(kj), for 1?t?n. Moreover, obtain upper bound dimension in which L is a nilpotent with one-dimensional derived superalgebra. It also provided several inequalities on as well analogue converse Schur’s theorem.

Generalized quantum statistics (GQS) associated to a Lie algebra or Lie superalgebra extends the notion of para-Bose or para-Fermi statistics. Such GQS have been classified for all classical simple Lie algebras and basic classical Lie superalgebras. In the current paper we finalize this classification for all exceptional Lie algebras and superalgebras. Since the definition of GQS is closely rel...

We establish that for the type I Lie superalgebras $sl(m/n)$ and $osp(2/2n)$, each Kac module admits a 1 parameter family of indecomposable double extensions. The result follows from explicit evaluation $H^1$ superalgebra cohomology valued in tensor product its dual.

We prove that the Duflo-Serganova functor DSx attached to an odd nilpotent element x of osp(m|2n) is semisimple, i.e. sends a semisimple representation M osp(m−2k|2n−2k) where k rank x. closed formula for DSx(L(λ)) in terms arc diagram λ.

The aim of this note is to completely determine the second homology group special queer Lie superalgebra sqn(R) coordinatized by a unital associative R, which will be achieved via an isomorphism between linear sln(R⊗Q1) and sqn(R).

We apply the techniques of quasideterminants to construct new families of Casimir elements for the general linear Lie superalgebra gl(m|n) whose images under the Harish-Chandra isomorphism are respectively the elementary, complete and power sums supersymmetric functions.
