Abstract

We show that for every weakly compact subset K of C[0,1] with finite Cantor-Bendixson rank, there is a reflexive Banach lattice E and an operator T:E→ C[0,1] such that K⊆ T(BE). On the other hand, we exhibit an example of a weakly compact set of C[0,1] homeomorphic to ωω+1 for which such T and E cannot exist. This answers a question of M. Talagrand in the 80's.
