摘要：
Nonreflexive Banach spaces that are complemented in their bidual by an L-projection-like preduals of von Neumann algebras or the Hardy space H-1-contain, roughly speaking, many copies of l(1) which are very close to isometric copies. Such l(1)-copies are known to fail the fixed point property. Similar dual results hold for c(0).
