The higher relation bimodule
Ibrahim Assem, M. Andrea Gatica, Ralf Schiffler
Given a finite dimensional algebra A of finite global dimension, we consider the trivial extension of A by the A-A-bimodule $\oplus_{i\ge 2} \Ext^2_A(DA,A)$, which we call the high…
Special biserial algebras with no outer derivations
Ibrahim Assem, Juan Carlos Bustamante, Patrick Le Meur
Let be a special biserial algebra over an algebraically closed field. We show that the first Hohchshild cohomology group of with coefficients in the bimodule vanishes i…
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…
