数值指标与对偶性
Numerical index and duality
摘要：
我们提出了一个例子的巴拿赫空间的数值指数是严格的大于的数值指数的对偶，给出了一个否定的答案，一直潜伏自七十年代初。我们还显示了一个特殊的情况下，其中的数字索引的空间和它的对偶之一重合。
英文摘要：
We present an example of a Banach space whose numerical index is strictly greater than the numerical index of its dual, giving a negative answer to a question which has been latent since the beginning of the seventies. We also show a particular case in which the numerical index of the space and the one of its dual coincide.
