contents Let $\mathfrak{g}=\mathfrak{gl}_{M|N}(\mathbb{k})$ be the general linear Lie superalgebra over an algebraically closed field $\mathbb{k}$ of characteristic zero. Fix an arbitrary even nilpotent element $e$ in $\mathfrak{g}$ and let $U(\mathfrak{g},e)$ be the finite $W$-superalgebra associated to the pair $(\mathfrak{g},e)$. In this paper we will give a complete classification of one-dimensional representations for $U(\mathfrak{g},e)$. To achieve this, we use the tool of shifted super Yangians to determine the commutative quotients of the finite $W$-superalgebras.

Let $\mathfrak{g}=\mathfrak{gl}_{M|N}(\mathbb{k})$ be the general linear Lie superalgebra over an algebraically closed field $\mathbb{k}$ of characteristic zero. Fix an arbitrary even nilpotent element $e$ in $\mathfrak{g}$ and let $U(\mathfrak{g},e)$ be the finite $W$-superalgebra associated to the pair $(\mathfrak{g},e)$. In this paper we will give a complete classification of one-dimensional representations for $U(\mathfrak{g},e)$. To achieve this, we use the tool of shifted super Yangians to determine the commutative quotients of the finite $W$-superalgebras.
