Abstract:IfA is a sgr-algebra on setX, thenl0infin(X,A) is a barrelled space of class chi0. IfA is an algebra, there are conditions which imply thatl0infin(X,A) is suprabarelled. Here, wheneverA is an algebra, we give conditions forl0infin(X,A) to be not barrelled which are related with the existence of non-trivial convergent sequences.Supported in part by DGICYT, project PB91-0407 and by the Institució Valenciana d'Estudis i Investigació, project 023.
