Coverings of Laura Algebras: the Standard Case (2010)
Assem, Ibrahim, Bustamante, Juan Carlos, Le Meur, Patrick
In this paper, we study the covering theory of laura algebras. We prove that if a connected laura algebra is standard (that is, it is not quasi-tilted of canonical type and its connecting components...

(Co)Homology theories for oriented algebras (2006)
Bustamante, Juan Carlos, Dionne, Julie, Smith, David
We study three different (co)homology theories for a family of pullbacks of algebras that we call oriented. We obtain a Mayer Vietoris long exact sequence of Hochschild and cyclic homology and...

The cohomology structure of string algebras (2004)
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, the Lie algebra...
Fundamental groups and presentations of algebras (2004)
Bustamante, Juan Carlos, Castonguay, Diane
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 algebra $A$ such that...
