We consider the classification problem for special classes of nilpotent Leibniz algebras. Namely, we consider “naturally” graded nilpotent $n$-dimensional Leibniz algebras for which the right multiplication operator (by the generic element) has two Jordan blocks of dimensions $m$ and $n-m$. Earlier, the problem of classifying such algebras was studied for $m4$. The present paper continues these studies for the case $m\ge4$.
Keywords: nilpotent Leibniz algebra, naturally graded Leibniz algebra, right multiplication operator, Lie algebra, nil-filiform Leibniz algebra, Jordan block, lower central series, nilpotency index, nil-index.
