On the Gabriel quiver of extensions of Leibniz algebras
arXiv:2308.04810
Abstract
We compute the Gabriel quiver of simple objects in the category of bimodules over a simple Leibniz algebra and over the trivial -dimensional Leibniz algebra. Vertices of the quiver are the classes of simple objects, arrows are given by the dimensions of Ext-groups.
