摘要
The Banach-Saks index of the separable part of the Marcinkiewicz spaces was calculated and estimated. A Banach space E of measurable functions on [0, 1] is called rearrangement invariant or symmetric. Kakutani proved that the uniform convexity of a space implies its Banach-Saks property. Baernstein constructed an example of a reflexive space with an unconditional basis that fails to have the Banach-Saks property. Banach and Saks proved that γ(Lp) = min(p, 2) and γ(lp) = p for all 1< p <∞.
