Maximal tori in $H H^{1}$ and the fundamental group

Benjamin Briggs, Lleonard Rubio y Degrassi

We investigate maximal tori in the Hochschild cohomology Lie algebra $H H^{1} (A)$ of a finite dimensional algebra $A$ , and their connection with the fundamental groups associated to p…

On the Lie algebra structure of $H H^{1} (A)$ of a finite-dimensional algebra $A$

Markus Linckelmann, Lleonard Rubio y Degrassi

Let $A$ be a split finite-dimensional associative unital algebra over a field. The first main result of this note shows that if the Ext-quiver of $A$ is a simple directed graph, th…
