B. Sims et Ma. Smyth, On some Banach space properties sufficient for weak normal structure and their permanence properties, T AM MATH S, 351(2), 1999, pp. 497-513
We consider Banach space properties that lie between conditions introduced
by Bynum and Landes. These properties depend on the metric behavior of weak
ly convergent sequences. We also investigate the permanence properties of t
hese conditions.
