【 摘 要 】

Let Lambda be a basic representation-finite biserial finite-dimensional k-algebra We describe a method for constructing a multiplicative basis and the bound quiver of the Ext-algebra E(Lambda) = U-m greater than or equal to 0 Ext(Lambda)(m)(Lambda/(r) under bar, Lambda/(r) under bar) of Lambda using the Auslander-Reiten quiver of Lambda.
