The fundamental group of an algebra with strongly simply connected Galois covering
Claudia Chaio, Diane Castonguay, Sonia Trepode
In this work, we prove that if a triangular algebra admits a strongly simply connected universal Galois covering for a given presentation then the fundamental group associated…
(m,n)-Quasitilted and (m,n)-Almost Hereditary Algebras
Diane Castonguay, Edson Ribeiro Alvares, Patrick Le Meur +1
Motivated by the study of (m,n)-quasitilted algebras, which are the piecewise hereditary algebras obtained from quasitilted algebras of global dimension two by a sequence of (co)ti…
Algebras Determined by Their Supports
Ibrahim Assem, Diane Castonguay, Marcelo Lanzilotta +1
In this paper, we introduce and study a class of algebras which we call ada algebras. An artin algebra is ada if every indecomposable projective and every indecomposable injective…
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…
