Resumen:
Given a finite dimensional algebra A of global dimension at most two, I. Assem,T. BrÄustle and R. Schiffler definned its relation extension algebra as the trivial extension A por el A bimódulo Ext^2_A(DA;A) where D = Homk(¡; k) is the standard duality between modA and modA^{op}. The objective of this talk is to describe the bound quivers of relation extensions of string algebras of global dimension at most two and show some properties which were obtained using this description.
