Abstract:IfA is a sgr-algebra on setX, thenl 0 infin (X,A) is a barrelled space of class chi0. IfA is an algebra, there are conditions which imply thatl 0 infin (X,A) is suprabarelled. Here, wheneverA is an algebra, we give conditions forl 0 infin (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.
