Resumen de CS-barrelled spaces

Wieslaw Sliwa, Marek Wójtowicz, Jerzy Kakol

• This note contains a proof of the following result: Let $E$ be a locally convex space. Every absorbing absolutely convex CS-closed subset of $E$ is a neighbourhood of zero in $E$ if and only if every sequentially closed linear map from $E$ into an arbitrary Banach space is continuous. Some consequences and remarks are also given.
