Resumo
In this note, we consider an algebra A which is a one-point extension
of another algebra B and we study the morphism of fundamental
groups induced by the inclusion of (the bound quiver of ) B into (that
of ) A. Our main result says that the cokernel of this morphism is a
free group and we prove some consequences from this fact.
