On bases, finite dimensional decompositions and weaker structures in Banach spaces Academic Article uri icon


  • This is an investigation of the connections between bases and weaker structures in Banach spaces and their duals. It is proved, e.g., that X has a basis if X* does, and that if X has a basis, then X* has a basis provided that X* is separable and satisfies Grothendieck's approximation property; analogous results are obtained concerning π-structures and finite dimensional Schauder decompositions. The basic results are then applied to show that every separable ℒ p space has a basis. © 1971 The Weizmann Science Press of Israel.
