Solvable Leibniz superalgebras whose nilradical has the characteristic sequence $(n-1, 1 \mid m)$ and nilindex $n+m$

Leibniz superalgebras with nilindex $n + m$ and characteristic sequence $(n-1, 1 \ | m)$ divided into four parametric classes that contain a set of non-isomorphic superalgebras. In this paper, we give complete classification solvable whose nilradical is nilpotent superalgebra m)$. We obtain condition for the value parameters such which they have extension. Moreover, Lie maximal given.
