| Abstract: | Every infinite dimensional Banach or Fréchet space X has a dense Baire (hence barrelled) subspace E of uncountable codimension such that every closed subspaee M of X with M E={0} is finite dimensional. This result solves negatively a problem raised recently by M. De Wilde and B. Tsirulnikov. |
