Representation theory of partial relation extensions
Ibrahim Assem, Juan Carlos Bustamante, Julie Dionne +2
Let C be a finite dimensional algebra of global dimension at most two. A partial relation extension is any trivial extension of C by a direct summand of its relation C-C-bimodule.…
Toupie algebra, some examples of laura algebras
Diane Castonguay, Julie Dionne, François Huard +1
We consider the bound quiver algebras whose ordinary quiver is that of a canonical algebra. We determine which of those algebras are hereditary, tilted, quasitilted, weakly shod or…
Laura string algebras
Julie Dionne
We give a simple combinatorial criterion allowing to recognize whether a string (or, more generally, a special biserial) algebra is a laura algebra or not. We also show that a spec…
Skew group algebras of piecewise hereditary algebras are piecewise hereditary
Julie Dionne, Marcelo Lanzilotta, David Smith
We show that the main results of Happel-Rickard-Schofield (1988) and Happel-Reiten-Smalo (1996) on piecewise hereditary algebras are coherent with the notion of group action on an…
(Co)Homology theories for oriented algebras
Juan Carlos Bustamante, Julie Dionne, David Smith
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…
