Second homology groups and universal coverings of Steinberg Leibniz algebras of small characteristic

Qifen Jiang, Ran Shen, Yucai Su

It is known that the second Leibniz homology group $H{L}_2(st{l}_n(R))$ of the Steinberg Leibniz algebra $st{l}_n(R)$ is trivial for $n\ge 5$. In this paper, we determine $HL_2(stl_n(R)…
