Abstract

Let LL be an (mn)(m\vert n)-dimensional nilpotent Lie superalgebra where m+n4m + n \geq 4 and n1n \geq 1. This paper classifies such nilpotent Lie superalgebras LL with a derived subsuperalgebra of dimension m+n2m+n-2 such that γ(L)=m+2n2dimM(L)\gamma(L) = m + 2n - 2 - \dim \mathcal{M}(L), where γ(L){0,1,2}\gamma(L) \in \{0, 1, 2\} and M(L)\mathcal{M}(L) denotes the Schur multiplier of LL. Furthermore, we show that all these superalgebras are capable.
