Proyecciones, Antofagasta, v. 24, n. 1, p. 79-87, May 2005.e- 0716-0917http://repositorio.bc.ufg.br/handle/ri/19280In 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.engAcesso AbertoFundamental groupsBound quiversPresentations of algebrasArtigo10.4067/S0716-09172005000100007
