On $mathrm{ID}^{*}$-superderivations of Lie superalgebras

Let $L$ be a Lie superalgebra over a field of characteristic different from $2,3$ and write $mathrm{ID}^{*}(L)$ for the Lie superalgebra consisting of superderivations mapping $L$ to $L^{2}$ and the central elements to zero. In this paper we first give an upper bound for the superdimension of $mathrm{ID}^{*}(L)$ by means of linear vector space decompositions. Then we characterize the $mathrm{ID}^{*}$-superderivation superalgebras for the nilpotent Lie superalgebras of class 2 and the model filiform Lie superalgebras by methods of block matrices.
