Resumen:
In this interesting paper the author studies the connection between the Hochschild cohomology groups of a $k$-algebra $A$ and those of incidence algebras associated to each presentation $Q(I,A)$ of $A$. The latter expression means that $A\cong{kQ}/{I}$, where $Q$ is a finite quiver, $kQ$ is the path algebra of $Q$, and $I$ is an admissible 2-sided ideal of $kQ$.
