On the Lie algebra structure of integrable derivations
Benjamin Briggs, Lleonard Rubio y Degrassi
Building on work of Gerstenhaber, we show that the space of integrable derivations on an Artin algebra forms a Lie algebra, and a restricted Lie algebra if contains a field…

The first Hochschild cohomology as a Lie algebra
Lleonard Rubio y Degrassi, Sibylle Schroll, Andrea Solotar
In this paper we study sufficient conditions for the solvability of the first Hochschild cohomology of a finite dimensional algebra as a Lie algebra in terms of its Ext-quiver in a…
