A NOTE ON THE FUNDAMENTAL GROUP OF A ONE-POINT EXTENSION
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...
