Resumen:
In this paper, we give a sufficient (which is also necessary under a compatibility hypothesis) condition on a set of arrows in the quiver of an algebra A so that A is a split extension of A/M, where M is the ideal of A generated by the classes of these arrows and A and A/M have compatible presentations. We also compare the notion of split extension with that of semiconvex extension of algebras.
