The cohomology structure of string algebras

Juan Carlos Bustamante

We show that the graded commutative ring structure of the Hochschild cohomology HH*(A) is trivial in case A is a triangular quadratic string algebra. Moreover, in case A isgentle,…

Fundamental groups and presentations of algebras

Juan Carlos Bustamante, Diane Castonguay

In this note, we investigate how different fundamental groups of presentations of a fixed algebra $A$ can be. For finitely many finitely presented groups $G_{i}$ , we construct an alg…

The classifying space of a bound quiver

J. C. Bustamante

We associate to a bound quiver (Q,I) a CW-complex which we denote by B(Q,I), and call the classifying space of (Q,I). We show that the fundamental group of B(Q,I) is isomorphic to…
